Built for your next step

Strengthen the security foundations of your startup product.

Security should not begin when an enterprise customer sends a security questionnaire.

We help startup teams identify and address important application and engineering security weaknesses before they become larger business risks.

Best suited for

  • SaaS startups
  • FinTech applications
  • AI applications
  • B2B software products
  • applications processing sensitive customer information
  • products preparing for enterprise customers
  • startups that have grown rapidly without dedicated security engineering

What success looks like

Understand the material risks in the agreed scope, validate selected fixes and leave with prioritised remediation actions for remaining findings.

Inside the engagement

Areas we assess

Authentication

  • session handling
  • password workflows
  • multi-factor authentication where appropriate
  • authentication architecture

Authorization

  • role-based access
  • privileged functions
  • object-level permissions
  • admin access

Secrets

  • API keys
  • environment credentials
  • database credentials
  • service tokens

Sensitive data

We review where relevant information is stored, processed, transmitted, and accessed.

Input validation

We assess application boundaries where untrusted input enters the system.

Dependency risk

We examine important third-party software and dependency-management practices.

API security

We review relevant API authentication, permissions, validation, and exposure.

Cloud permissions

We examine unnecessary privilege and access where cloud scope is included.

Logging and auditability

We assess whether important actions and security-relevant events can be investigated.

Secure development practices

We identify weaknesses in development, testing, configuration, and deployment processes.

Inside the engagement

Our approach

The objective is not simply to run an automated vulnerability scanner and deliver a report.

We combine automated tooling where appropriate with engineering review, system context, configuration analysis, architecture understanding, and prioritised remediation.

Inside the engagement

Risk classification

Critical

Requires immediate investigation.

High

Material security weakness requiring priority remediation.

Medium

Meaningful weakness that should be addressed.

Low

Hardening or engineering improvement.

Inside the engagement

Important scope note

Product Security Hardening is an engineering security improvement service.

It is not automatically equivalent to:

  • formal penetration testing
  • regulatory certification
  • PCI DSS certification
  • ISO 27001 certification
  • SOC 2 certification
  • guaranteed vulnerability-free software

Where specialist certification or penetration testing is required, that should be separately scoped.

Scope & boundaries

Scope, systems, access and acceptance criteria are agreed before work starts. Selected remediation is limited to the agreed engagement.

From first conversation to handover

A clear path to delivery

  1. 01

    Technical Discovery

    We understand your product, current technology stack, business priorities, known problems, and desired outcome.

  2. 02

    Agree the scope

    Define the systems, repositories, access, review areas or implementation work, deliverables and acceptance criteria for your engagement.

  3. 03

    Review & engineer

    Assess the agreed product areas, document evidence and carry out any engineering improvements included in scope, with regular progress reviews.

  4. 04

    Prioritise & hand over

    Walk through findings and completed work, confirm next priorities and hand over the agreed documentation and recommendations.

The details that matter

Before we get started

A few things to know about scope, timing and working together.

Is this a fixed-price package?

The displayed prices are indicative. We agree a defined scope, acceptance criteria and a project quote before work starts. Requests beyond that scope are estimated separately.

What do you need from our team?

A product or operations contact, access to the agreed systems and documentation, representative test data, and timely feedback. We confirm access and integration dependencies before scheduling delivery.

When does the delivery timeline begin?

The target delivery window is 2–5 weeks, starting once scope, access and dependencies are ready. Third-party approvals or changes to the agreed scope can affect timing.

What happens after delivery?

We hand over the agreed deliverables and documentation with a walkthrough for your team. Further features, monitoring and ongoing maintenance can be scoped as a separate engagement.

Prices are indicative GBP project ranges. Final scope, deliverables, acceptance criteria and price are agreed before work starts. Timelines assume defined scope, available technical access and compatible third-party integrations. Vendor, infrastructure, regulatory and licensing costs are excluded.
