• Penetration testing firms (62) →

  Penetration testing firms run authorized, hands-on tests of web applications, APIs, cloud infrastructure, mobile products, or networks, then document exploitable paths and remediation priorities.

• vCISO firms (54) →

  A vCISO is a part-time outside security leader who owns the program: policy, risk decisions, vendor questions, and the relationship with your auditor, without a full-time hire.

  You need this if Someone needs to be accountable for security decisions, and a full-time CISO is not the right size for where you are yet.

• ISO 27001 firms (38) →

  ISO 27001 consultants build and run the Information Security Management System the certification requires, often alongside SOC 2 for companies pursuing both.

  You need this if A customer or region requires ISO 27001 specifically, or you want SOC 2 and ISO 27001 to share one evidence program instead of two.

• Compliance consulting firms (75) →

  Compliance consultants run the SOC 2 program day to day: control ownership, evidence collection, vendor risk, and coordination with your auditor, broader than a one-time readiness push.

  You need this if You want an ongoing outside partner running the program year to year, not just a push to your first audit.
