About NullFortis

Security That Thinks Like An Attacker

NullFortis is a security firm. We run the tests, lead the exercises, and handle the incidents: penetration testing, red team operations, cloud & web application security, digital forensics, and compliance advisory. Attack surface monitoring is one part of what we do, not the whole story. Alongside it, we build and run our own security tools, because the best way to understand a defence is to have already broken one like it.

What We Do

Two Ways We Keep You Ahead

Hands-on security services for when you need people in the loop, and in-house tools for when you need something running continuously.

Security Services

Penetration TestingManual and automated testing against real attack techniques, not just a checklist scan.
Red Team OperationsFull-scope adversary simulation that tests your detection and response, not just your defences.
Cloud & Web Application SecurityConfiguration reviews, code-level testing, and cloud misconfiguration audits across AWS, Azure, and GCP.
Digital Forensics & Incident ResponseCourt-admissible investigation and containment for when something's already gone wrong.
Compliance & GRC AdvisoryPractical guidance toward ISO 27001, PCI DSS, SOC 2, and similar frameworks, without the busywork.

Security Tools We Build

NprintFingerprints every visitor and flags VPNs, bots, and impossible-travel patterns before they reach your site.
ESPMContinuously monitors SPF, DKIM, and DMARC and stops scammers from impersonating your company by email.
DomTailDiscovers and tracks every website and server your company owns, including the ones everyone forgot about.
Threat MapVisualizes cyberattacks happening around the world in real time, with related attacks linked to a single actor.
FlowGroundSimulates real attacks against any architecture you build, so you know what actually stops a breach before you ship it.

Why NullFortis

What Makes Us Different

We Test Like Real Attackers

Not just automated scanners. Our findings come from the same techniques, tools, and persistence a real adversary would use against you.

We Build What We Can't Buy

Nprint, ESPM, DomTail, Threat Map, and FlowGround exist because our own engagements needed them. We use them ourselves before we ever offer them to a client.

We Stay Engaged After The Report

A finding isn't the finish line. We work through remediation with your team until the vulnerabilities are actually gone.
