Hire Cybersecurity Expert for SaaS Companies
Senior, direct, no layers

In saas companies, a trial user hits a paywall bug on day one, a billing change double-charges a team, and a feature ships with a regression nobody caught before release. The useful question is not whether the business could be attacked, but which attack would hurt most: the one that stops trial sign-up and onboarding, or the one that quietly copies customer account data, usage data, payment details, and product telemetry.

The engagement works through trial sign-up and onboarding and subscription billing and plan changes in turn, checking who can do what, what is logged, and where a single compromised account could reach. a customer tenant breach, a leaked API key, and a compromised billing integration is the scenario the defences are tested against, not a generic checklist.

Start narrow: trial sign-up and onboarding end to end, from who can log in to whether a backup actually restores, and a fix list the business can work through without hiring a security team. Discuss that first workflow directly; wider scope follows only if the first piece earns it.

The systems in play are the product itself, billing platforms, analytics, support desks, and status pages. The work starts from those systems, because replacing tools the team knows rarely fixes the underlying problem.

The work is done on the systems the business already runs: the product itself, billing platforms, analytics, support desks, and status pages. New tooling is recommended only where an existing gap cannot be closed by configuration, because a tool nobody maintains is worse than no tool.

Where a vendor controls the system, the engagement documents the risk and the questions to put to the vendor, rather than pretending the business can fix what it does not control.

What changes is the incident conversation: instead of discovering during a crisis that nobody knows who decides, the business has walked through a customer tenant breach, a leaked API key, and a compromised billing integration once already and knows the first three moves.

That is the standard this engagement is measured against: not a launch announcement, but a workflow the business still uses months later, maintained by its own team with documentation handed over at the end. Browse all hire engagements or discuss your workflow directly.
