Client Stories

Trusted by teams who can't afford to be compromised.

“

Darkside completely changed how we approach security. We went from one annual pentest to testing every quarter across our entire stack. The portal is slick and the reports are genuinely useful — not just a PDF dump.

CTO, FinVault

“

The subscription model just makes sense. We found a critical vulnerability in week two that would have cost us massively if exploited. That single finding paid for the whole year.

James Okonkwo

Head of Engineering, Brixly

“

As a healthcare company, we have serious compliance obligations. Darkside's reporting format and the AI-powered analysis makes it so much easier to demonstrate our security posture to auditors.

LC

Laura Chen

CISO, MediTrack

“

Turnaround times are genuinely impressive. We submit a request, it's approved same day, and we have preliminary findings within a week. That speed matters when you're shipping fast.

Tom Hargreaves

VP Engineering, Stackform

“

The client portal is really well thought out. My whole team can see request status, access reports, and track findings without chasing anyone by email. It just works.

Security Lead, Aerodash

“

As a startup, we couldn't justify a full-time security hire. Darkside gives us enterprise-level testing at a price that makes sense for our stage. It's become a core part of our roadmap planning.
