Signs you need this now.

Most breaches don't come from sophisticated attacks; they come from ordinary, well-known gaps — weak authentication flows, missing access controls, unpatched dependencies, secrets sitting in plaintext. These issues are usually straightforward to fix once identified, but nobody's assigned to actually go through the system and close them before something happens.

01

A security question came from a customer or investor and nobody had a good answer

An enterprise prospect's security questionnaire or an investor's due diligence request surfaced questions about data handling and access control the team can't confidently answer. The deal or round is now waiting on a response nobody can write.

02

Dependencies haven't been updated in years

Core libraries and frameworks are running old versions with known, published vulnerabilities, and nobody's been assigned to own the upgrade path. Each month that passes adds to a growing list of disclosed exploits sitting in production.

03

Access control was never really designed, it just accumulated

Permissions and roles were added ad hoc as features shipped, and nobody can currently produce a clear answer to who can access what. A departing employee or a bug in permission logic is one incident away from a real exposure.

Scope

What you get.

Security assessment of the application and infrastructure

A focused review of authentication, authorization, data handling, and dependency risk, prioritized by actual exploitability rather than a generic checklist.

Authentication and access control hardening

Fixes to session handling, password policies, and role-based access so permissions match intent instead of accumulated defaults.

Dependency and patch remediation

Outdated and vulnerable dependencies identified and upgraded, with breaking changes handled as part of the work rather than left for someone else to untangle.

Data handling and secrets management fixes

Sensitive data and credentials moved out of plaintext, logs, and source control into proper secrets management and encryption where they belong.

Security headers and infrastructure configuration

HTTP security headers, CORS policy, rate limiting, and server configuration reviewed and corrected against current best practice.

Remediation report for compliance or diligence use

Documentation of what was found and fixed, written in a form usable for customer security questionnaires or investor technical diligence.

How it works

Four steps, no mystery.

01

Quick scoping call

A short call (or async over WhatsApp) to understand what you're working with and what "done" actually looks like for you.

02

Fixed scope, no surprises

A clear written plan of what's included and how long it takes, before any work starts.

03

The actual work

Progress you can see, not a black box. You get updates as milestones land, not just a status report at the end.

04

Handover

Everything documented and handed over cleanly, with a walkthrough so your team isn't stuck waiting on me for routine changes.

Questions

Frequently asked.

Yes, fixes are staged and tested against a non-production environment first wherever possible, with production changes scheduled deliberately rather than applied live and unverified.
