The security review is the predictable obstacle in every enterprise SaaS sales cycle. The size and sophistication of the review varies by industry and customer size, but every enterprise buyer beyond $25K ACV will conduct some form of security assessment before signing.
The founders who treat security as a "we'll handle it when asked" problem spend 4-6 weeks per enterprise deal scrambling to produce documentation that could have been prepared once. The founders who invest in the security baseline before they need it sail through reviews that stall competitors.
The security baseline for enterprise-aspiring SaaS:
SOC 2 Type II report. This is the single most impactful security investment for enterprise sales velocity. The audit takes 3-6 months and costs $15-40K depending on auditor and scope. It replaces months of questionnaire back-and-forth with a third-party validated report. Every enterprise security team accepts it. Many reduce their questionnaire to zero when you present it.
Standard security questionnaire responses. The top enterprise security questionnaire formats (CAIQ, SIG, the Salesforce questionnaire, the Google questionnaire) cover 80%+ of what you'll be asked. Build pre-filled responses to all of them. Store them in a security portal (Safebase, OneTrust, or a simple Notion page) that you share with prospects.
Penetration test results. An annual pen test with a reputable firm demonstrates security investment and generates documentation that satisfies security team requirements.
Data processing agreement template. A standard DPA reviewed by privacy counsel, available to sign with minor negotiation. Having your DPA ready to share reduces legal review cycles significantly.
Incident response policy. A documented plan for what you do when a security incident occurs. Every enterprise prospect asks for this.
The investment: $40-80K per year for SOC 2 maintenance, pen testing, and legal review. The return: weeks of time saved per enterprise deal and enterprise contracts that otherwise wouldn't close.
