Security Tools We Build And Use Ourselves

Everything here started as something our own team needed on real engagements. No jargon below, just what each tool actually does for you.

Nprint

Nprint fingerprints every visitor to your site, including those attempting to disguise their identity, and flags VPN use, spoofed locations, and bot-like behavior automatically. Repeat visitors are recognized across sessions, and risky traffic can be blocked or challenged before it reaches your application.

Persistent Visitor IdentificationRecognizes returning visitors across sessions, even after a browser fingerprint change.
Risk DetectionAutomatically detects VPN use, location spoofing, and bot-like interaction patterns.
Surface LockdownRestrict access to approved visitors only, ideal for private betas or internal tools.
Real-Time AlertsImmediate notification when suspicious activity is detected, not after the fact.

Attack CorrelationGroups related attacks to reveal a coordinated campaign, not scattered noise.
Track Your Own DomainsRegister your own domains to see exactly who's been probing or attacking them.
Stakeholder-Ready ReportingClear, visual reporting that's easy to brief to non-technical stakeholders.

FlowGround

FlowGround simulates real-world attacks against any architecture you build, from a five-minute proof of concept to a full production topology. Business Mode translates the outcome into plain-language risk for stakeholders, while Technical Mode exposes the raw request, the exploit path, and the exact control that stopped it — so your team validates defenses before an adversary tests them for real.

Build Any ArchitectureDrag and drop AWS, Azure, GCP, and Cloudflare services into a real topology, from a quick example to your own production design.
30+ Real Attack LabsJWT tampering, SQL injection, XSS, CSRF, and replay attacks, run against the architecture you actually built.
Intercept & Edit RequestsA Burp Suite-style request editor and a visual JWT decoder let you modify a live request and watch the defense react in real time.
Business + Technical ModesPlain-language explanations for stakeholders, packet-level detail for engineers, same simulation either way.
