Exploit, then fix
The vaccine for the AI era.
AI agents that attack your business the way a hacker would, then fix what they find.
Every era of computing brought a new kind of attack.
And every time, the old protection wasn’t enough. Something new had to be built.
1987, Antivirus
Personal computers arrive on every desk, and viruses spread from disk to disk.
1991, Firewall
Computers start talking to each other. One program spreads to thousands in a day.
2009, Cloud security
Data moves to rented servers, where one wrong setting leaves the door open.
Now, the age of AI
Attackers use AI too. The answer for this era is still missing.
What changed
Attackers now strike in hours.
Most fixes still take weeks.
Medicine arrives after the damage. A vaccine arrives before it.
Exploit + Fix
Exploit, then fix. That’s the name, and that’s the job.
ExFyx tests your websites, apps, servers, cloud and code around the clock, safely and under strict rules. When it finds a weakness, it proves an attacker could really use it, then writes and tests the fix, so the door is closed before anyone walks through it. Your team only steps in to approve.
01The team
A team of AI agents.
Atlas leads. Rook attacks. Echo proves. Patch fixes.
Ten specialists, each with one job, hand work straight to each other. You don’t manage ten agents: you talk to ExFyx as one colleague, in Slack or on the dashboard.
Tap an agent to see what it’s working on.
Your team, live
128 hand-offs02Attack
Attacks like a real hacker.
Your apps, code and cloud. Safely, only where you allow.
Scout maps everything you expose online, every day. Rook tests your live apps and APIs, Nova reads your code and Sky checks your cloud, the way an attacker would, inside the scope and the hours you set.

03Prove and fix
Proof, then the fix.
Every weakness proven real. Every fix written and tested.
Echo repeats every attack on its own before you ever see it, and Rook checks whether small flaws chain into a break-in. Patch writes the fix as a ready-made code change. You approve it, and Echo retests and closes it.
Watch it play out, or open any tab and approve the fix yourself.

04Watch
Safe and compliant.
The newest threats, checked against everything you run.
Every three hours, Iris reads the latest threat intelligence, including invite-only sources built up over five years, and checks it against your software. If you’re affected, it proves it and starts the fix. Quill maps every finding and fix to SOC 2, ISO 27001, GDPR, PCI DSS, HIPAA and India’s DPDP Act.

05Background
Quietly, around the clock.
The work of a full security team, in the background.
No dashboards to dig through. ExFyx only speaks up when you need to act, and when a new threat lands, the answer is usually waiting before you ask. Ask it anything, the way you’d ask a colleague.

AnsweringIf you lead security
A security team that reports to you.
See what you own, what’s weak, and exactly what an attacker could exploit from the outside. Spend your time on strategy instead of chasing alerts.
Safe by design
Broad testing. Narrow authority.
ExFyx can test a great many things, but it’s only ever allowed to do a few tightly controlled things to each of them. You set the scope and the hours, and a person on your side signs off.
Most AI tools are told the rules and trusted to follow them. ExFyx’s rules are locked in, and every action is checked before it runs. It’s the difference between asking a contractor not to go into the bedroom and locking the bedroom door.
- It never tests anything outside the scope you set.
- It never runs without your written permission.
- It never reports a problem it hasn’t reproduced.
- It never sees your real passwords or keys.
- Your data stays in your region, and never trains any model.
- A person on your side always makes the final call.
