Maintaining SOC 2 Compliance
Getting your first SOC 2 report is the hard part. But maintaining it year-over-year requires ongoing investment in tooling, people, and processes. Annual maintenance typically costs 30 to 40% of the initial compliance investment.
Annual Ongoing Cost Breakdown
Annual surveillance audit
$8,000 to $25,000
Annual
SOC 2 Type 2 reports cover a 12-month period, so a new audit report is issued each year. Audit fees for renewal are typically lower than the initial engagement but still significant.
GRC platform
$12,000 to $40,000/year
Annual subscription
Tools like Vanta, Drata, Secureframe, or Tugboat Logic automate evidence collection, map controls to criteria, and maintain audit trails. Pricing scales with employee count and number of integrations.
Security tooling
$8,000 to $30,000/year
Annual subscription
SIEM, endpoint detection, vulnerability scanning, and access management tooling needed to maintain controls. Partially overlaps with tools you would run for security reasons regardless of SOC 2.
Penetration testing
$6,000 to $20,000/year
Annual
Most auditors recommend or require annual penetration testing as evidence of vulnerability management. Scope varies from application-only to full internal and external testing.
Internal compliance staff
$15,000 to $60,000/year
Ongoing (fractional or full-time)
Maintaining SOC 2 requires someone to own evidence collection, vendor reviews, policy updates, and audit coordination. Early-stage companies often use a fractional security or compliance officer.
External readiness support
$3,000 to $15,000/year
Ad hoc or annual
Some companies retain a compliance consultant for a small number of days per year to review policy updates, advise on new controls, and support pre-audit preparation.
Ongoing Compliance Activities Calendar
| Activity | Cadence | Owner |
|---|---|---|
Evidence collection GRC platforms automate most evidence collection, but periodic manual verification of access reviews, training completion, and backup testing must be scheduled and documented. | Continuous (monthly captures) | Compliance / Engineering |
Access reviews All system access rights must be reviewed and confirmed or revoked at least quarterly. Results must be documented with reviewer name and date. | Quarterly | Engineering / IT |
Vendor risk reviews Review the security posture of critical and data-processing vendors. Update DPAs and vendor assessments. Check that vendor SOC 2 or ISO 27001 reports remain current. | Annual | Security / Legal |
Security awareness training All employees must complete security awareness training at least annually. Records of completion must be maintained and available to auditors. | Annual | HR / Security |
Policy review and update All SOC 2 policies must be formally reviewed and updated at least annually. Changes must be approved by management and communicated to relevant staff. | Annual | Security / Legal |
Incident response testing Tabletop exercises or live drills of the incident response procedure. Results must be documented. Auditors increasingly ask for evidence of testing, not just the plan. | Annual | Engineering / Security |
Vulnerability scanning Automated vulnerability scans of production infrastructure. Findings must be triaged, prioritised, and remediated within the SLAs defined in your vulnerability management policy. | Continuous or quarterly | Engineering |
Backup restoration testing Backup procedures must be tested by actually restoring from backup. Many organisations document backup processes but never test restoration. Auditors ask for restoration evidence. | Quarterly | Engineering |
How to Reduce Annual Maintenance Cost
- Use a GRC automation platform (Vanta, Drata, Secureframe) to automate evidence collection and reduce manual work by 60 to 80%.
- Integrate your tooling stack with the GRC platform at implementation to minimise manual data gathering at audit time.
- Negotiate multi-year audit pricing with your CPA firm at the time of initial engagement.
- Build compliance activities into engineering sprint cycles rather than treating them as separate overhead.
- Publish an internal compliance calendar so all owners know their responsibilities and deadlines in advance.
- Reuse existing security controls wherever possible to serve multiple frameworks (SOC 2, ISO 27001, GDPR) simultaneously.
