The problem
Most breaches use ordinary weaknesses: a missing permission check, an unvalidated input, an outdated library.
- Any logged-in user can open another customer's record by changing a number in the address.
- Forms accept whatever is typed, including code.
- The application relies on libraries with known vulnerabilities.
- Passwords and keys sit in the source code.
One overlooked check can expose every customer record you hold.
The solution
Web and mobile applications built and hardened so that a mistake in one place does not expose everything.
Authentication
Sign-in, password rules, multi-factor options and session handling.
Authorisation
Checks on every request that the user may do what they ask.
Input validation
All incoming data checked on the server before it is used.
Secure APIs
Authenticated, rate-limited endpoints that return only what is needed.
Workflow
How it works
- 01
Review
Code, configuration and dependencies are examined.
- 02
Threat model
We map what an attacker would target, and how.
- 03
Fix
Weaknesses are corrected in code and configuration.
- 04
Test
Fixes are verified and attack cases re-run.
Maintain
Updates and checks become part of each release.

Illustrative scenarios
How it looks in practice
- Healthcare
A patient portal lets users view reports. The review confirms each request is checked against the signed-in patient, so one person cannot open another's report by guessing a link.
- Education
A student portal handles fee payments. Input checks, session limits and payment-callback verification are added before the admission season.
These scenarios show how the service applies in a business like yours. They are not client results.
Why Scale Lab IT
One method behind every project.
- BUILDSecurity designed into the application, not added after an incident.
- AUTOMATEDependency and code checks run with every release.
- SECUREEvery request verified; secrets kept out of the code.
- SCALENew features inherit the same checks.
Implementation
How the project runs
- 01Code and architecture reviewHow the application is built, and where trust is assumed.
- 02Threat modellingThe data that matters and the likely routes to it.
- 03RemediationFixes applied in order of risk.
- 04VerificationSecurity testing of the corrected application.
- 05Release practiceChecks added to your normal development process.
Common questions
Can you secure an application another team built?
Yes. We review the existing code and configuration, then fix issues directly or work alongside your developers.
Will the fixes change how the application works for users?
Most are invisible. Where behaviour changes, for example stronger sign-in, we agree it with you first.
Does this make the application completely secure?
No honest provider can promise that. It removes the known weaknesses and puts checks in place so new ones are caught early.
How often should this be repeated?
After major changes and at least once a year, with dependency checks running continuously.
