Building got faster than reviewing
A working application can now exist in days. The security architecture behind it — who can read what, which endpoints are reachable, where secrets live — is a separate discipline that does not happen automatically.
ExpediApp Security Assurance
Independent validation for software that shipped quickly.
Rapid-development and AI-assisted tools can produce functional applications before security architecture, access controls, data policies and operational safeguards have been independently validated. ExpediApp closes that gap.
Why this matters now
Speed creates security debt that nobody has looked at.
This is not a criticism of the tools. They do what they promise, and they do it well. Shipping quickly and validating independently are simply two different activities — and the second one is easy to skip.
The gaps are structural, not sloppy
The issues we find are rarely careless code. They are defaults that were reasonable during prototyping and never revisited: permissive database roles, session checks that trust the wrong signal, endpoints outside the protection they appear to sit behind.
Nothing fails loudly
An application with an unreviewed access model looks identical to one with a sound access model. It serves pages, it takes submissions, it sends email. The difference only becomes visible when someone looks — or when someone else does.
What we assess
The areas an application actually gets caught on.
Access and identity
- Authentication and session assessment
- Authorization and protected-route validation
- Rate limiting and abuse controls
Data and storage
- Database permissions and row-level security
- Audit-trail and data-integrity validation
- Mobile API and storage review
Application surface
- API exposure analysis
- Input validation and injection defenses
- File-upload and email security
Supply chain and platform
- Secrets and environment-variable review
- Dependency and supply-chain checks
- Cloud deployment configuration
Sanitized case study
Findings from our own assurance process.
We run the same assurance process against our own systems. These are the findings it surfaced in our internal RFP platform, together with the remediation and how each fix was proven against the running system.
This is an internal case study, not an independent certification or a third-party audit. It contains no credentials, URLs, schema detail or reproduction steps.
| Area | Before | After hardening | Verified by |
|---|---|---|---|
| Session integrity | Presence of a cookie was treated as proof of authentication. | Cryptographically signed sessions with a bounded lifetime. | Forged and expired sessions rejected in production checks. |
| Endpoint authorization | Sensitive endpoints were not covered by the route matcher. | Middleware plus an independent handler-level authorization check. | Handlers deny unauthenticated calls even when invoked directly. |
| Database exposure | Public database role held broad read and write privileges. | Anonymous privileges revoked; access moved server-side only. | Anonymous access confirmed denied against the live database. |
| Write scope | A draft endpoint accepted arbitrary fields from the request body. | Explicit allowlist of writable fields. | Protected fields provably unchanged after an override attempt. |
| Response freshness | Authenticated responses could be served from cache. | Dynamic, no-store responses on every authenticated route. | State transitions observed reflected immediately after commit. |
| Duplicate side effects | Repeating a submission repeated its outbound notifications. | Atomic processing claim plus a durable, idempotent delivery record. | Repeated retries produced no additional delivery. |
| Silent failure | A document-generation failure was caught and discarded. | Classified failure stored and surfaced in the administrative trail. | Failure visible to operators instead of reported as success. |
| Evidence | Security posture was asserted from code inspection. | Behavioral test suite covering each control. | Each control re-verified against the running system. |
What that exercise actually taught us
Two of the findings were only visible because we tested behaviour rather than reading code — and one initial diagnosis was wrong and had to be corrected when the evidence contradicted it. That is the argument for independent validation with proof attached, and it is how we work on client systems too.
How it runs
Scope, assess, report, remediate, verify.
- 01
Scope
Agree the application, environments and boundaries. Read-only access is the default starting point.
- 02
Assess
Work through the capability areas below, recording each finding with its business impact and a severity.
- 03
Report
A prioritized report you own, written to be actionable by your team with or without us.
- 04
Remediate
Optionally, we implement the fixes — smallest change that closes the issue, no opportunistic rewrites.
- 05
Verify
Each fix is proven with a behavioral test and re-checked against the running system, not signed off from code review.
Engagement levels
Start small. Go further only if it is worth it.
Most engagements begin with a Snapshot. Pricing is scoped per application rather than published, because a single-form marketing site and a multi-tenant operational platform are not the same piece of work.
- 01
Security Snapshot
A time-boxed independent assessment of one application, delivered as a prioritized findings report you own.
- 02
Security Hardening Sprint
We remediate the validated findings and provide before-and-after evidence for each one.
- 03
Continuous Security Assurance
Ongoing review as the application changes: dependency monitoring, deployment checks and regression testing.
- 04
Enterprise Application Governance
Portfolio-wide visibility for teams responsible for many internal, vendor-built or AI-assisted applications.
Scope of claims
What this is not.
- We are not a certification body, and an assessment is not a compliance audit.
- We do not claim applications built with any particular tool are inherently unsafe.
- We do not publish client findings, and we do not use one engagement as marketing for the next.
- We report what we found and what we tested — not a guarantee that nothing else exists.
Have something in production that has never been reviewed?
That is the common case, not an unusual one. A Snapshot tells you where you actually stand, in language you can take to a board or a customer.
