Top Cybersecurity Assessments & Hardening Companies

Cybersecurity assessment and hardening firms find the weaknesses an attacker would use, then close them. Assessments include external and internal penetration tests, web application and API testing, cloud configuration reviews, vulnerability scanning, phishing simulations and risk assessments mapped to NIST CSF or ISO 27001. Hardening is the follow-through: patching, removing default settings, tightening identity and access, and applying CIS Benchmarks to servers, endpoints and cloud accounts. Companies hire them before a SOC 2 audit, after an incident, or when a customer or insurer asks for evidence.

Compare the firms below on tester certifications, a redacted sample report, and whether they retest after fixes or help with the hardening.
