Source-code security analysis · every line read
An AI can find the hole in your product in minutes.
What took a skilled attacker days now takes anyone a $20 subscription and a sentence — and they can run it against ten thousand companies at once. Your product isn’t being targeted. It’s being enumerated. DefensiveAI reads every line of your code and finds it first.
This is not a future problem.
One engagement, four findings a scanner would have scored low.
Anonymized · recent review
During a recent review for a large organization, we found four small mistakes. An authorization check that could be bypassed. A secret buried in a JavaScript bundle. A broken OIDC login flow. And the application’s entire front end shipped to the browser before login — handing anyone the complete list of API endpoints.
A vulnerability scanner would flag some of these. Low severity, each.
Together, they left the entire database open to the internet. Read and write. Trivial to cover your tracks. An AI agent pointed at the public portal would have chained them in minutes — chaining is what agents do. It’s the worst vulnerability we’ve seen, and it was made of ordinary mistakes.
There is no way to know whether anyone got there first.
What people get wrong about AI security
The worry is usually the chatbot — someone tricking it into saying something it shouldn’t. Or a vague future where machines outthink us. The real change is smaller and already here: expert-level attack capability became a commodity. The cost of finding a vulnerability dropped to almost nothing. The number of attempts went the other way. Your defenses didn’t move.
How it works
Three steps, and a report you can act on.
Access
Read-only repository access, or an archive. Confidential by default and in writing.
Analysis
Every line of code, read by a system built for it — recursive decomposition, roll-up synthesis, nothing discarded. Then every observation validated by a human analyst.
Delivery
A validated report of what matters to your code and your business — not a list. Remediation guidance, and if you want, the fixes. Most engagements deliver within two weeks.
Three doors
Run it yourself, or have us do it.
Run it yourself
FreeThe analysis, on your machine, against your own code. Nothing leaves your computer.
Have us run it
AssessmentEvery line read, every observation validated by an analyst, and a report tied to what it means for your business.
Keep it running
ContinuousThe analysis runs again as you ship, and an analyst reviews what changed.
Offers
What each one costs.
Assessment
One-time · from $3,500Every line read, every finding validated, a report you can act on and hand to an auditor.
Continuous
Monthly · from $600The analysis keeps running as you ship. An analyst reviews what changed. No meetings.
Fixes
Per finding, or hourlyWe implement the remediations as pull requests your team reviews.
Need it for a security questionnaire or SOC 2?
A customer’s procurement team sent a questionnaire. An auditor wants evidence of a security review. An Assessment produces a validated report and a summary letter you can hand to either.
People
Every engagement is reviewed by a named analyst.
