Case Studies & Blogs
Writeups, case studies, and research from our security team.
We test with the full picture
Give us your code and setup, and KLUE learns how your app actually works, then finds the flaws hiding in your own logic, not just the obvious, already-known ones.
We test with limited access
With just a few logins, KLUE blends an outsider's view with a little inside knowledge to show how small gaps chain together into a real breach.
We test like a real attacker
Starting with nothing but your public address, KLUE probes your systems exactly the way an outside attacker would, then proves what it can reach.
Real bugs.
Real engagements.
Whether we start with full access to your code or nothing at all, KLUE finds real vulnerabilities and proves they can be exploited, not just a list of maybes.
See how KLUE engagesWhat we offer.
Engagements that ship proof.
Three ways we keep you secure: reviewing your code, checking your cloud and Microsoft 365 setup, and testing your systems the way a real attacker would. Every engagement is run by certified experts and powered by KLUE.
Code Review & App Testing
We review your source code and test your live apps by hand, finding the logic flaws automated scanners miss and proving them with working exploits.
- Source code & infrastructure review
- Web app testing
- API testing
- Mobile apps (iOS + Android)
- Internal network testing
Cloud & Microsoft 365 Reviews
We check how your cloud and Microsoft 365 are set up, looking for weak settings, loose access, and paths an attacker could use to reach your data.
- AWS, Azure & Google Cloud review
- Microsoft 365 review
- Login & access controls
- Data-leak paths
- CIS / NIST compliance mapping
Real-World Attack Testing
Full engagements at whatever access level fits, from a no-knowledge attacker simulation to a deep, full-access review of your code and infrastructure.
- Real-world attack simulation
- Full-access code & infrastructure review
- Partial-access testing
- Continuous testing in your pipeline
- Proven, end-to-end attack paths
New-client offer · Limited time
30% off your first 3-hour engagement.
A focused discovery run for new clients. Walk away with working proofs-of-concept and a written summary, delivered same day.
Track record.
Not pitch deck.
Real, working exploits, publicly reported security flaws, and senior certified engineers on every engagement. We ship proof, not promises.
Thinks, doesn't just scan
KLUE works through each target like a senior tester would, exploring, testing ideas, and proving what's real, instead of matching against a list of known issues.
Proof, not guesswork
Every finding comes with a working proof. We confirm it can actually be exploited or rule it out, no maybes, no theoretical risk.
Same-day first proof
First working proof delivered within 24 hours of kickoff. The full report follows in days, not weeks, so issues get fixed before they ship.
Certified senior testers
Every engagement is led by an OSCP, CRTO, CPTS, or CREST-certified engineer, with continuous training to stay ahead of the latest attacker techniques.
Public track record
Five-plus security flaws publicly reported and credited across popular open-source software. Coordinated, responsible, and recognized by the community.
Built for ongoing coverage
Test once, after every release, or continuously, KLUE adapts to your schedule instead of forcing you onto a fixed one.
