After a fundraise: 5 cybersecurity actions to prioritize

Published on 2026-03-197 min readFlorian

You just raised. Security isn't your priority. It should be.

After a fundraise (Seed, Series A, Series B), the priority is scaling: hiring, acquiring customers, developing the product. Security falls to the back burner. That's precisely the riskiest moment.

Why? Because you're about to triple your user base with an application that has never been audited. Existing flaws will be exploited at larger scale. And your new enterprise clients will demand security evidence.

Action 1: Audit before scaling

Have your application audited within 30 days of closing. Not in 6 months when you have 10,000 users. Flaws found now cost 10x less to fix than after a public data breach.

Our external review identifies critical flaws within 48h. It's compatible with the post-fundraise pace.

Action 2: Secure your CI/CD

Your deployment pipeline is the critical path. If an attacker gains access, they modify your production code directly. Priority actions: enable 2FA on GitHub/GitLab for the entire team, protect the main branch with mandatory reviews, scan dependencies automatically (Dependabot, Snyk), and never store secrets in code (use secured environment variables).

Action 3: Monitor dependencies

Your application probably has hundreds of npm or pip dependencies. Each is a potential attack vector. Enable automatic security alerts on your package manager. Update critical dependencies within a week of an advisory.

Action 4: Prepare for client questionnaires

Your sales team will target enterprise accounts. Security questionnaires will arrive. Prepare now: an audit report, a basic security policy, and a breach notification procedure. These unblock deals.

Action 5: Document your security posture

Your investors will want to know you're managing cyber risk. Document the security measures in place, audits performed, flaws remediated, and the improvement plan. It's also useful for future rounds — technical due diligence is increasingly scrutinized.

The ideal timeline

Day 0 to Day 30: external review of the existing application

Day 30 to Day 60: fix critical and high flaws

Day 60 to Day 90: set up monitoring and secure CI/CD

Quarter 2: first re-test and preparation for client questionnaires

Our post-fundraise offer

External Review (€1,900) for a quick diagnosis, or Full Audit (€4,200) for a report usable with your clients and investors. Quarterly monitoring (€3,600/year) to track your security evolution during scaling.
