Introducing ARTEMIS Browser Mode: Red-Team Your AI Applications Like a Human Would

Introducing ARTEMIS Browser Mode: Red-Team Your AI Applications Like a Human Would

You know that feeling when you spend three weeks reverse-engineering API calls from Chrome DevTools, finally get your red-teaming script working perfectly... and then they push an update that breaks everything?

Yeah. We've all been there.

The API Integration Death March We've All Lived

It's Monday morning. Your AI red-teaming automation that worked flawlessly last Friday is now throwing 401 errors. The vendor "upgraded" their authentication flow over the weekend. Again.

You fire up the browser inspector, start copying curl commands, and realize the new flow requires some undocumented header that's dynamically generated client-side. By Wednesday, you've got it working. By Friday, they've changed something else.

Sound familiar? You're not alone. Every security engineer has lived this nightmare.

The worst part? While you're babysitting broken integrations, real attackers are having multi-turn conversations with your AI systems, uploading malicious files, and chaining attacks through the actual user interface. They're not using your APIs - they're using your product the way it was meant to be used.

What Your API Tests Miss (And Attackers Don't)

Let's be honest about what API-based testing actually covers:

What your automated tests see:

  • Single text prompts

  • JSON request/response pairs

  • Whatever endpoints are documented

  • One-shot injection attempts

What real attackers do:

  • Build trust through 15-message conversations

  • Upload "innocent" PDFs with embedded prompts

  • Use voice inputs to bypass text filters

  • Chain social engineering with technical exploits

  • Test edge cases your API docs never mention

Remember that time you found a critical vulnerability by just... clicking around the UI for 10 minutes? That wasn't luck. That was the fundamental difference between how humans think and how APIs work.

The Maintenance Hell You Know Too Well

Raise your hand if you've ever:

  • Spent more time fixing red-team scripts than actually finding vulnerabilities

  • Had your security automation break during a live demo

  • Written "TODO: Update auth flow" in your code for the third time this month

  • Wished you could just test the damn thing like a normal user 

You're not an API integration engineer. You're a security professional. Yet somehow half your time goes chasing breaking changes instead of finding actual security issues.

ARTEMIS Browser Mode: Red Teaming From the Front Door

We built ARTEMIS Browser Mode because we were tired of the same pain. Instead of fighting APIs, we test AI applications exactly how attackers do - through the browser, like a human.

Here's how it works:

1. Log In Once, Test Everything

No more reverse-engineering authentication flows. You log in once (or provide temporary auth), and ARTEMIS takes over from there. When they change their login flow next week, you won't even notice.

2. Test Like Attackers Actually Attack
  • Multi-turn conversations that build context and trust

  • File uploads with adversarial content hidden in seemingly innocent documents

  • Voice and image inputs that bypass your text-based filters

  • Social engineering chains that your single-request API tests would never catch

  • Edge cases discovered through actual UI exploration

3. Zero Maintenance Overhead

When the vendor updates their interface, ARTEMIS adapts automatically. No more emergency Slack messages about broken tests. No more weekend integration fixes.

Real Security Testing, Not Integration Theater

Here's what changes when you stop fighting APIs and start testing like attackers:

Before (API Hell):

  • 3 weeks to get initial integration working

  • Constant maintenance after every vendor update

  • Testing only documented endpoints

  • Missing multi-modal attack vectors

  • 70% time on maintenance, 30% on actual security

After (ARTEMIS Browser Mode):

  • 10 minutes to start testing

  • Automatic adaptation to interface changes

  • Complete attack surface coverage

  • Discovery of real attack chains

  • 10% time on setup, 90% on finding vulnerabilities

The "Wait, It's That Simple?" Moment

Getting started takes minutes, not weeks:

  • Choose your login method - interactive walkthrough or auth file

    Login using auth.json



    Login using interactive walkthrough


  • Select attack vectors - prompt injection, jailbreaks, multi-modal attacks, file-based exploits



  • Let ARTEMIS run - it tests like a human attacker would



  • Get actionable results - risk scores, compliance mapping, clear remediation steps

No integration burden. No scripts to maintain. No fighting with curl commands in your spare time.

What Security Engineers Are Saying

"We tried like 4 different AI red-teaming tools. Every single one required custom auth integrations that broke constantly. I was basically a full-time API integration engineer. ARTEMIS just works out of the box through the browser. Found stuff on day one that we'd been missing for months." - Security Engineer at UK-based FinTech

"Our vendor kept changing their OAuth flow and all our testing would just die. I'd get pinged at 2am because automated scans failed again. Haven't touched a single integration since switching - it just tests through the UI like an actual human would." - Principal Security Engineer at AI unicorn (Series C)

"Honestly? I was spending more time in Postman debugging auth headers than actually doing security work. Now I just point ARTEMIS at our app and it finds the weird edge cases that only come up when you actually use the product normally." - Security Lead at public HRTech company

The Bottom Line

You became a security engineer to find vulnerabilities, not to babysit API integrations.

ARTEMIS Browser Mode gives you comprehensive AI red-teaming that:
✅ Tests the complete attack surface (UI + backend + model)
✅ Adapts automatically to application changes
✅ Discovers attack chains that API testing misses
✅ Reduces maintenance overhead by 80%+
✅ Actually works the way security testing should

Ready to Stop Fighting APIs?

Book a demo and see ARTEMIS Browser Mode find vulnerabilities your API tests are missing.

Book a demo now → 15 minutes to see what you've been missing

Because life's too short to spend it debugging authentication flows.
