How React Native Hermes Turned Apps from a Data Goldmine into Fort Knox

Picture this: You’ve built the perfect React Native restaurant discovery app. Thousands of restaurants, millions of reviews, carefully curated photos, exclusive deals, and proprietary recommendation algorithms that took your team two years to perfect. Your React Native Hermes-powered app is gaining traction, investors are interested, and everything seems to be going according to plan.

Then your head of engineering walks into your office with a concerned look.

“We have a problem,” they say, pulling up network monitoring dashboards. “Someone is systematically scraping our entire restaurant database. They’re hitting our APIs with perfect requests, bypassing our rate limiting, and they seem to know exactly how our authentication works.”

Your stomach drops. “How is that possible? We have API security in place.”

“They reverse-engineered our mobile app. Found all our API endpoints, figured out our request signing mechanism, and now they’re using our own authentication patterns against us. They’ve downloaded our entire restaurant database, all our reviews, and they’re probably building a competing service as we speak.”

This isn’t a hypothetical nightmare. This is happening right now to thousands of businesses whose React Native apps are essentially open books, revealing not just their source code, but the keys to their entire data kingdom.

But here’s the thing: if you’re running a modern React Native app with Hermes enabled, this attack just became exponentially more difficult. Not impossible—nothing ever is—but difficult enough that most attackers will abandon the effort and look for easier targets.

The problem? Most business leaders have no idea this security transformation even happened, or why it matters for protecting their most valuable asset: their data.

The Great API Heist: Why Your Old React Native App Was a Treasure Map

Let me tell you about the dark side of mobile app development that nobody talks about in the boardroom. Before Hermes became the default JavaScript engine in React Native 0.70, every React Native app was essentially shipping with a detailed instruction manual for how to steal its data.

Here’s how the old system worked, and why it was a disaster waiting to happen:

When you built a React Native app using JavaScriptCore (JSC), your entire application logic was bundled into a JavaScript file that lived inside your app package. This file contained everything: your API endpoints, your authentication mechanisms, your request formatting logic, and often even hardcoded secrets that developers thought would be “safe” inside the app.

Think of it like this: imagine you’re running a restaurant chain, and every time you open a new location, you also publish a detailed manual explaining exactly how to access your supplier databases, how to replicate your ordering system, and what passwords to use for your inventory management. That’s essentially what pre-Hermes React Native apps were doing.

The attack process was embarrassingly simple:

Step 1: Download the App

Cost: $0 (it’s free on the app store)

Time: 2 minutes

Skill level: Can you click “Install”?

Step 2: Extract the JavaScript Bundle

Cost: $0 (basic file extraction tools)

Time: 30 seconds

Skill level: Can you unzip a file?

Step 3: Beautify the Code

Cost: $0 (free online tools)

Time: 10 seconds

Skill level: Can you paste text into a website?

Step 4: Find the API Gold Mine

Time: 5-30 minutes

Skill level: Can you search for “api” or “endpoint” in a text file?

And just like that, an attacker would have:

• Every API endpoint your app uses
• The exact format of your API requests
• Your authentication headers and token handling
• Any custom encryption or signing mechanisms
• Rate limiting bypass techniques
• Database query patterns
• Business logic and algorithms

This wasn’t just theoretical. Security researchers regularly demonstrated this vulnerability, and the tools to exploit it were freely available and required no specialized knowledge.

The API Vulnerability Cascade: From Code to Data Breach

Once an attacker has your API information, the damage cascades quickly. Let’s walk through what happens next, using our restaurant app example:

Phase 1: Reconnaissance

With your decompiled JavaScript bundle, the attacker can see exactly how your app communicates with your servers. They discover endpoints like:

• /api/restaurants/search
• /api/restaurants/{id}/details
• /api/reviews/list
• /api/user/favorites
• /api/admin/restaurant/create (oops, that shouldn’t be in the mobile app)

Phase 2: Authentication Bypass

Your app probably implements some form of API authentication. Maybe it’s JWT tokens, maybe it’s custom headers, maybe it’s a proprietary signing mechanism. Doesn’t matter—it’s all visible in the JavaScript bundle. The attacker can see:

• How tokens are generated and refreshed
• What headers are required for authenticated requests
• Any custom encryption or hashing algorithms
• Rate limiting workarounds built into the app

Phase 3: Data Extraction

Now the attacker can craft perfect API requests that look exactly like they’re coming from your legitimate app. They can:

• Download your entire restaurant database
• Scrape all user reviews and ratings
• Extract pricing information and deals
• Copy your recommendation algorithms
• Access user data (depending on your API design)

Phase 4: Business Impact

The stolen data can be used to:

• Build a competing service with your data
• Sell your database to competitors
• Manipulate your platform (fake reviews, spam listings)
• Undercut your pricing with perfect market intelligence
• Launch targeted attacks against your users

This entire process, from downloading your app to having a complete copy of your data, can happen in under an hour.

SSL Pinning: The Security Theater That Doesn’t Work

Now, you might be thinking, “Wait, don’t we have SSL pinning to prevent this?”

SSL pinning is a security technique where your app is hardcoded to only trust specific SSL certificates, preventing man-in-the-middle attacks. It’s a good security practice, but it doesn’t solve the reverse engineering problem—in fact, it often makes things worse.

Here’s why SSL pinning fails against determined attackers:

The Frida Problem

Tools like Frida allow attackers to perform dynamic instrumentation on running apps. They can hook into your app’s SSL pinning code at runtime and simply disable it. The process looks like this:

1. Install your app on a rooted/jailbroken device
2. Use Frida to inject code that bypasses SSL pinning
3. Set up a proxy to intercept all network traffic
4. Watch your API requests flow by in plain text

The Source Code Problem

Even worse, if your SSL pinning implementation is visible in your JavaScript bundle (which it was in pre-Hermes React Native), attackers can understand exactly how it works and craft more sophisticated bypasses.

The False Security Problem

SSL pinning gives developers a false sense of security. They think, “We have SSL pinning, so our APIs are safe,” while completely ignoring the fact that their entire API communication logic is sitting in a readable JavaScript file.

SSL pinning is like putting a really good lock on your front door while leaving your house key under the welcome mat with a note explaining how to use it.

The Scraping Epidemic: When Your Data Becomes Their Business

One of the most devastating applications of React Native reverse engineering is automated data scraping. This isn’t just about copying your app—it’s about systematically extracting the valuable data that makes your business work.

The Economics of Scraping

Data scraping has become a massive industry because data is valuable. Your restaurant database, your user reviews, your pricing information—all of this has real economic value. Companies will pay significant money for:

• Competitive intelligence (what are your competitors charging?)
• Market research (what restaurants are popular in specific areas?)
• Lead generation (contact information for restaurant owners)
• SEO content (reviews and descriptions for their own sites)

The Technical Challenge

Web scraping is relatively straightforward—attackers can inspect HTML, analyze network requests, and build scrapers using standard web technologies. Mobile app scraping is different. Scrapers need to understand:

• Your app’s authentication mechanisms
• The exact format of API requests
• Rate limiting and anti-bot measures
• Custom headers and encryption

In the old React Native world, all of this information was sitting right there in the JavaScript bundle. Building a scraper became a matter of reading documentation rather than reverse engineering.

The Scale Problem

Once attackers understand your API structure, they can scrape at massive scale. They’re not limited by the constraints of your mobile app—they can make thousands of requests per minute, systematically downloading your entire database.

We’ve seen cases where attackers scraped millions of records from mobile apps, then sold that data to competitors or used it to build competing services. The original app developers had no idea it was happening until they noticed unusual server load patterns.

Security Through Obscurity: When Hiding Actually Works

Security experts usually hate the concept of “security through obscurity”—the idea that hiding how something works makes it more secure. And they’re usually right to hate it, because most implementations are naive and easily defeated.

But React Native apps often implement a more sophisticated version of this concept, and Hermes makes it genuinely effective.

The Custom Authentication Pattern

Many successful apps implement custom authentication mechanisms that go beyond standard JWT tokens or API keys. For example:

1. Request Signing: The app generates a hash of the request payload combined with a secret key and timestamp
2. Custom Headers: Proprietary headers that must be present and correctly formatted
3. Encryption Layers: Additional encryption of sensitive data before transmission
4. Behavioral Patterns: Requests that must follow specific sequences or timing patterns

Here’s a real-world example of how this might work:

// This would be visible in pre-Hermes React Native

function signRequest(payload, timestamp) {
    const secret = "app_secret_key_2024";
    const combined = payload + timestamp + secret;
    const hash = customHashFunction(combined);

    return {
        'X-App-Signature': hash,
        'X-App-Timestamp': timestamp,
        'X-App-Version': '2.1.4'
    };
}

In the old JSC world, this entire function would be visible in the JavaScript bundle. An attacker could:

• See the secret key
• Understand the hashing algorithm
• Replicate the signing process
• Bypass your authentication entirely

The Hermes Advantage

With Hermes, this same logic gets compiled into bytecode that looks something like:

LoadParam 0
LoadParam 1
GetGlobalObject
LoadConstString "app_secret_key_2024"
CallBuiltin customHashFunction
CreateObject
PutById "X-App-Signature"
...

This is dramatically harder to understand and reverse-engineer. An attacker would need to:

1. Identify the specific Hermes bytecode version
2. Find or build compatible decompilation tools
3. Successfully decompile the authentication logic
4. Understand the resulting pseudo-code
5. Reconstruct the original algorithm

For most attackers, this cost-benefit analysis doesn’t work out. They’ll move on to easier targets.

The Moving Target Defense

The security gets even better when you consider that Hermes bytecode formats change regularly. Even if an attacker successfully reverse-engineers your authentication mechanism, their tools and knowledge become obsolete when you update your React Native version.

This creates what security researchers call “economic deterrence”—the cost of attack exceeds the potential reward for most threat actors.

Enter Hermes: The Bouncer Your Data Always Needed

Now let’s talk about how Hermes fundamentally changed this security landscape. When Meta introduced Hermes and made it the default JavaScript engine for React Native, they didn’t just improve performance—they accidentally created one of the most effective mobile app security improvements in recent history.

The Compilation Revolution

Hermes switches from Just-in-Time (JIT) compilation to Ahead-of-Time (AOT) compilation. Here’s what that means for your data security:

The Old Way (JavaScriptCore):

1. Write your JavaScript code (including all API logic)
2. Bundle it up as readable JavaScript
3. Ship it to users
4. Hope nobody looks inside

The New Way (Hermes):

1. Write your JavaScript code
2. Compile it into bytecode during the build process
3. Ship only the bytecode to users
4. Your original source code never leaves your development environment

The difference is like the gap between sending someone your diary versus sending them a message written in an ancient language that only a few scholars can read—and those scholars keep changing the language every few months.

The Bytecode Barrier

Hermes bytecode isn’t just obfuscated JavaScript—it’s a completely different format that requires specialized tools and knowledge to understand. Your API endpoints, authentication logic, and business rules are compiled into a binary format that looks like this:

89 48 45 52 4D 45 53 00 00 00 60 00 00 00 04 00 00 00 0A 00 00 00 52 65 61 63 74 4E 61 74 69 76 65 00 00 00

Good luck finding your API endpoints in that.

The Decompiler’s Dilemma: Why Reverse Engineering Hermes Is a Nightmare

Let’s dive deep into why Hermes is so resistant to reverse engineering, because understanding this will help you appreciate the security benefits.

The Version Fragmentation Problem

Every version of React Native ships with a specific version of Hermes, and each Hermes version uses a different bytecode format. This creates a constantly moving target for attackers.

Here’s what the current landscape looks like:

The Tool Fragmentation Problem

The reverse engineering tools that do exist are fragmented, incomplete, and constantly playing catch-up:

hermes-dec: The most popular tool, maintained by P1 Security. It’s a constant work-in-progress that must be manually updated for each new bytecode version. The GitHub repository is filled with issues like “Support for bytecode version 96?” and “Tool crashes on latest React Native.”

hbctool: A community tool that supports only older bytecode versions (59, 62, 74, 76). Completely useless for modern React Native apps.

hbcdump: Meta’s official tool, designed for compiler developers, not attackers. It only works with the exact bytecode version it was built for.

This fragmentation means that even if an attacker finds a working decompiler, it probably won’t work with your specific app version.

The Real-World Impact: Case Studies in Hermes Security

Let’s look at some real-world examples of how Hermes has changed the security landscape:

Case Study 1: The Restaurant App

A popular restaurant discovery app was being systematically scraped by competitors. Before Hermes:

• Attackers could see all API endpoints in the JavaScript bundle
• Authentication mechanisms were completely visible
• Scraping tools were built in days
• Millions of restaurant records were stolen

After upgrading to Hermes:

• API endpoints were compiled into bytecode
• Authentication logic became opaque
• Scraping attempts dropped by 90%
• Remaining attacks required significantly more resources

Case Study 2: The E-commerce Platform

An e-commerce app was losing competitive advantage because rivals could see their pricing algorithms and inventory management logic. The Hermes upgrade:

• Protected proprietary pricing calculations
• Hid inventory prediction algorithms
• Secured supplier API integrations
• Reduced competitive intelligence gathering

Case Study 3: The Financial Services App

A fintech startup was concerned about API security and compliance. Hermes provided:

• Protection of transaction processing logic
• Obscured fraud detection algorithms
• Secured customer data access patterns
• Improved compliance posture for enterprise sales

iOS vs Android: The Security Spectrum Explained

To fully understand Hermes’s security benefits, we need to compare it to the broader mobile security landscape.

Android: The Wild West

Native Android apps without additional protection are embarrassingly vulnerable to reverse engineering. The standard attack process uses two main tools:

APKTool: Unpacks the APK file and extracts all resources, including the compiled code in Smali format (Android’s assembly language).

JADX: The real weapon. JADX can decompile Android APKs back to readable Java code with shocking accuracy. Security researchers report that JADX output is often “almost the same Java file that we created firstly.”

This means that a typical Android app’s source code, business logic, and API integration patterns are completely visible to anyone with basic reverse engineering skills.

iOS: The Fortress

iOS apps are significantly more secure due to Apple’s architectural decisions:

• Mandatory App Sandboxing: Each app runs in isolation
• Hardware-Level Security: Features like the Secure Enclave protect sensitive data
• Closed Ecosystem: Apple controls the entire stack
• Code Signing: Apps must be cryptographically signed

However, iOS isn’t impenetrable. Tools like Hopper and Ghidra can still decompile iOS binaries, and the Reddit iOS programming community regularly discusses reverse engineering techniques. As one developer noted: “Yes, it’s possible to decompile iOS apps, but it requires more specialized knowledge and tools compared to Android.”

React Native with Hermes: The Sweet Spot

React Native Hermes-powered apps occupy a unique position in this security spectrum:

• More secure than traditional web-based approaches
• More secure than pre-Hermes React Native
• More secure than unprotected native Android apps
• Approaching the security level of native iOS apps

Most importantly, Hermes provides consistent security across both platforms. Your API logic gets the same bytecode protection whether it’s running on Android or iOS.

The Scraper’s Nightmare: How Hermes Breaks Automated Data Extraction

Data scraping represents one of the most significant business threats enabled by mobile app reverse engineering. Let’s examine how Hermes specifically disrupts scraping operations:

Traditional Scraping Process

1. Reverse Engineer the App: Extract API endpoints and authentication mechanisms
2. Replicate Authentication: Build tools that can authenticate like the real app
3. Automate Requests: Create scripts that systematically extract data
4. Scale the Operation: Run scrapers across multiple IP addresses and user accounts

How Hermes Disrupts Each Step

Step 1 Disruption: API endpoints and authentication logic are compiled into bytecode that’s specific to your React Native version. Scrapers can’t easily find this information.

Step 2 Disruption: Even if scrapers identify some endpoints, they can’t see the complete authentication mechanism. Custom headers, signing algorithms, and encryption patterns are hidden in the bytecode.

Step 3 Disruption: Without understanding the complete API contract, automated requests often fail or trigger anti-bot measures.

Step 4 Disruption: The increased complexity makes scraping operations economically unfeasible for many attackers.

The Economic Impact

Consider a restaurant app with 100,000 restaurant listings. Each listing might be worth $1-5 in data value. A successful scraper could extract $100,000-500,000 worth of data in a few hours.

With Hermes protection, the cost of building that scraper increases dramatically:

• Reverse engineering time: Days to weeks instead of hours
• Specialized skills required: Security researchers instead of web developers
• Tool development: Custom bytecode analysis instead of standard web scraping
• Maintenance overhead: Tools break with each app update

For many attackers, this cost-benefit analysis no longer makes sense.

The API Security Deep Dive: Beyond Basic Authentication

Let’s examine specific API security patterns that Hermes helps protect:

Pattern 1: Request Signing

Many apps implement custom request signing to prevent API abuse:

function signRequest(method, url, payload, timestamp) {
    const secret = getAppSecret();
    const message = method + url + payload + timestamp;
    const signature = hmacSHA256(message, secret);

    return {
        'X-Signature': signature,
        'X-Timestamp': timestamp
    };
}

Pre-Hermes: This entire function is visible in the JavaScript bundle.

Post-Hermes: The signing logic is compiled into bytecode, hiding the algorithm and secret.

Pattern 2: Dynamic API Endpoints

Some apps use dynamic endpoint generation to make scraping harder:

function buildEndpoint(baseUrl, resource, userContext) {
    const hash = generateContextHash(userContext);
    return `${baseUrl}/api/v2/${hash}/${resource}`;
}

Pre-Hermes: Scrapers can see the endpoint generation logic.

Post-Hermes: The endpoint construction is opaque to attackers.

Pattern 3: Behavioral Authentication

Advanced apps implement behavioral patterns that must be followed:

function authenticateWithBehavior(action, previousActions, timing) {
    if (!validateActionSequence(previousActions, action)) {
        return null;
    }
    if (!validateTiming(timing)) {
        return null;
    }
    return generateAuthToken(action, context);
}

Pre-Hermes: The behavioral validation logic is completely visible.

Post-Hermes: Attackers can’t understand what behavioral patterns are required.

The Enterprise Security Angle: Compliance and Risk Management

For enterprise customers and regulated industries, Hermes provides significant compliance and risk management benefits:

Intellectual Property Protection

• Source code is not present in distributed applications
• Proprietary algorithms are protected from casual inspection
• Trade secrets remain secret

Data Protection Compliance

• Reduced risk of data access pattern exposure
• Protection of customer data handling logic
• Obscured database query patterns

Competitive Intelligence Prevention

• Business logic is not easily discoverable
• Pricing algorithms are protected
• Market strategies remain confidential

Audit and Compliance Benefits

When security auditors ask about mobile app security, you can demonstrate:

• Ahead-of-time compilation protecting source code
• Version-specific bytecode preventing long-term reverse engineering
• Reduced attack surface compared to traditional approaches

The Technical Deep Dive: Understanding Hermes Bytecode

For the technically inclined, let’s examine what Hermes bytecode actually looks like and why it’s so difficult to reverse-engineer:

Bytecode Structure

Hermes bytecode is a binary format that includes:

• Header information (version, metadata)
• String table (compressed and indexed)
• Function definitions (as bytecode instructions)
• Constant pool (literals and references)

Instruction Set

Hermes uses a custom instruction set optimized for JavaScript execution:

• LoadParam: Load function parameter
• GetGlobalObject: Access global scope
• CallBuiltin: Call built-in function
• CreateObject: Create new object
• PutById: Set object property

The Decompilation Challenge

Converting these instructions back to readable JavaScript requires:

1. Understanding the instruction semantics
2. Reconstructing control flow
3. Inferring variable names and types
4. Rebuilding high-level constructs

Each step is complex and error-prone, especially as bytecode versions change.

The Moving Target Defense: Version Evolution

One of Hermes’s most powerful security features is its constantly evolving bytecode format. Let’s examine this in detail:

Version Release Cadence

React Native releases new versions approximately every 3-4 months, each potentially including Hermes updates. This creates a regular cycle of bytecode format changes.

Backward Compatibility

Hermes intentionally breaks backward compatibility between major versions. This means:

• Old decompilers don’t work with new bytecode
• Attackers must constantly update their tools
• The reverse engineering community fragments across versions

The Maintenance Burden

For attackers, this creates an ongoing maintenance burden:

• Tools must be updated for each new version
• Expertise becomes obsolete quickly
• The cost of maintaining reverse engineering capabilities increases over time

Real-World Attack Scenarios and Hermes Protection

Let’s examine specific attack scenarios and how Hermes provides protection:

Scenario 1: The Competitor Intelligence Gathering

Attack: A competitor wants to understand your pricing algorithm and market strategy.

Pre-Hermes: Download app, extract JavaScript bundle, find pricing logic in minutes.

With Hermes: Must reverse-engineer bytecode, understand custom algorithms, likely to give up.

Scenario 2: The Data Broker Operation

Attack: A data broker wants to scrape your user-generated content for resale.

Pre-Hermes: Easily find API endpoints and authentication in JavaScript bundle.

With Hermes: Cannot easily discover API structure, scraping becomes economically unfeasible.

Scenario 3: The Malicious Clone

Attack: Someone wants to create a malicious clone of your app with ads or malware.

Pre-Hermes: Copy JavaScript bundle, modify as needed, republish.

With Hermes: Cannot easily extract and modify business logic, cloning becomes much harder.

Scenario 4: The API Abuse Campaign

Attack: Bad actors want to abuse your APIs for spam or fraud.

Pre-Hermes: Understand API structure from JavaScript, build automated abuse tools.

With Hermes: API structure is opaque, abuse tools are harder to build and maintain.

The Limitations: What Hermes Cannot Do

It’s important to understand Hermes’s limitations to set appropriate expectations:

Runtime Analysis

Sophisticated attackers can still analyze app behavior at runtime using tools like:

• Frida for dynamic instrumentation
• Proxy tools for network traffic analysis
• Debuggers for memory inspection

Determined Nation-State Actors

Government-level attackers with unlimited resources can still reverse-engineer Hermes apps, but this is beyond the threat model for most businesses.

Social Engineering

No technical security can protect against attackers who convince employees to provide access or information.

Server-Side Vulnerabilities

Hermes protects client-side code but doesn’t fix backend security issues like SQL injection or authentication bypasses.

Physical Device Access

Attackers with physical access to unlocked devices can potentially extract data regardless of code protection.

The Implementation Guide: Securing Your React Native App with Hermes

If you’re convinced that Hermes provides valuable security benefits, here’s how to implement it:

Step 1: Check Your Current Setup

# Check React Native version
npx react-native --version

# Check if Hermes is enabled (Android)
grep -r "enableHermes" android/app/build.gradle

# Check if Hermes is enabled (iOS)
grep -r "hermes_enabled" ios/Podfile

Step 2: Enable Hermes (if not already enabled)

For React Native 0.70+, Hermes is enabled by default. For older versions:

Android (android/app/build.gradle):

project.ext.react = [
    enableHermes: true
]

iOS (ios/Podfile):

:hermes_enabled => true

Step 3: Verify Hermes is Working

// Add this to your app to verify Hermes is running
const isHermes = () => !!global.HermesInternal;

console.log('Hermes enabled:', isHermes());

Step 4: Clean and Rebuild

# Clean everything
npx react-native clean

# Rebuild for Android
npx react-native run-android

# Rebuild for iOS
npx react-native run-ios

Step 5: Verify Bytecode Generation

Check that your app bundle contains bytecode instead of JavaScript:

• Android: Look for .hbc files in the APK
• iOS: Check the app bundle for Hermes bytecode

The Business Case: ROI of Hermes Security

Let’s quantify the business value of Hermes security:

Implementation Cost

• Development time: 1-4 hours (mostly testing)
• Infrastructure changes: None
• Ongoing maintenance: Minimal
• Total cost: $500-2000 (depending on team size)

Risk Mitigation Value

• IP theft prevention: $100K-10M+ (depending on business)
• Data scraping prevention: $50K-1M+ annually
• Competitive intelligence protection: $25K-500K+
• Compliance and audit benefits: $10K-100K+

ROI Calculation

Even conservative estimates show ROI in the thousands of percent range. The cost of enabling Hermes is minimal, while the potential losses from IP theft or data scraping can be enormous.

The Future: What’s Next for React Native Security

As React Native continues to evolve in the competitive mobile development landscape, the security landscape continues to evolve. Here’s what we can expect:

Hermes Evolution

The Bottom Line: Security as a Business Enabler

Here’s the fundamental truth about mobile app security: it’s not just about preventing bad things from happening. It’s about enabling good things to happen.

When your intellectual property is protected, you can invest more confidently in R&D. When your data is secure from scrapers, you can build sustainable competitive advantages. When your APIs are resistant to abuse, you can focus on serving legitimate users instead of fighting off attackers.

Hermes didn’t just make React Native apps faster—it made them more defensible. In a world where data is the new oil and intellectual property is increasingly valuable, that defensibility might be the difference between building a sustainable business and watching your innovations get copied by competitors who didn’t do the hard work of creating them.

The security revolution is here. The question is: are you part of it, or are you still leaving your data vault unlocked?

The choice is yours, but the clock is ticking. Every day you delay is another day your competitors might be studying your API patterns, your business logic, and your data structures. Every day is another opportunity for scrapers to systematically extract the valuable information that makes your business unique.

Hermes offers you a chance to close that window, to protect what you’ve built, and to compete on innovation rather than hoping your secrets stay secret.

The tools are available. The implementation is straightforward. The ROI is undeniable.
