THE CHALLENGE

A Clean Pentest Report That Wasn't Actually Clean

Manual pentests are a snapshot. A skilled consultant spends two weeks probing your systems, writes a report, and moves on to the next client. They test what they can reach in the time they have.

Attackers don't have a two-week budget. They have automated tools that probe indefinitely, iterate on every parameter, and wait until they find something. The economics are completely different.

  • They hired a reputable security firm. Paid $15,000. Got a clean report with a handful of low-severity findings.
  • Three months later, their staging API endpoint was hit by an automated crawler. SQL injection. Customer data exposed.
  • The breach cost them one major customer and triggered an emergency response that consumed two full engineering sprints.
  • The manual pentest had tested the same endpoint. They just tested it differently than the attacker did.
THE SOLUTION

Continuous Testing That Thinks Like an Attacker

Striker doesn't test once and move on. It tests every deployment, every endpoint, at machine speed - the same way real attackers probe systems, not the way consultants do it.

  • Striker connected to their API via a staging environment token - 15-minute setup.
  • Ran continuous fuzzing against all 47 endpoints, including the one that had been manually tested.
  • Found a parameter-level SQL injection in the order history endpoint in under an hour. The kind of thing you only catch by iterating at machine speed.
  • Generated a full remediation report with proof-of-concept payload, impact assessment, and fix recommendation.
  • Now runs every time a new deployment goes to staging. The manual pentest model is retired.
“The manual pentest gave us a false sense of security. Striker found the exact vulnerability within an hour of connecting. Same endpoint. Same parameter. The consultant just didn't iterate enough.”
