Security
Enterprise-grade cybersecurity, built in from day one
Most agencies treat security as a checklist they run at launch. We run penetration tests for a living, so we build the way we would want to find a site when we are the ones attacking it.
The baseline
What “security built in” actually means
Four things, on every site, whether or not you ever buy a penetration test from us. None of them are line items on your quote.
Hardened response headers
A Content Security Policy that is actually restrictive, HSTS, frame and MIME-type protections, and a sane referrer policy. Configured per site rather than copied from a generator — a CSP that permits everything is decoration.
No exposed keys. Ever.
Anything shipped to browser JavaScript is readable in the network tab regardless of how clean the code is. Secrets live server-side in environment variables. Only publishable keys reach the client, backed by row-level security on the database.
Audited dependencies
A modern site pulls in hundreds of packages, and most breaches walk in through one of them. Advisories are reviewed and patches are shipped and verified — not left sitting as an unread alert in a repository nobody opens.
Tested before you own it
Every site gets a full security pass in the 14-day build, before handover. It is a standard build stage, not an upsell — which is what lets us say every site we ship has been security-tested and mean it literally.
Why it is different here
Built by people who break into websites
Carpathian is a penetration testing agency as well as a web development one. That is not a credential we mention for flavour — it changes what gets built.
Checklist compliance asks “did we set the header?” An attacker asks “what does this application let me do that it did not intend to?” Those produce different websites. Access control that looks correct in code review falls over the moment someone changes an ID in a URL. A form that validates properly in the browser accepts anything at all if the server trusts the client. Business logic — the order of operations in a checkout, a booking, a password reset — is where real breaches live, and no scanner has an opinion about it.
We build with those failure modes in mind because we spend the rest of our time exploiting them in other people’s applications. The defensive work is informed by the offensive work, which is the entire argument for buying both from one team.
Optional extra
Always-on protection, not an annual snapshot
A penetration test is a photograph of one moment. Your site changes, your dependencies change, and new vulnerability classes arrive every month. Continuous testing is the retainer answer to that.
Added to your monthly retainer, autonomous agents test your live site on a schedule and work the way a human tester does — not the way a scanner does.
Enumerate the attack surface
The agents map what is actually reachable — the web application, its APIs, the infrastructure behind it and its cloud configuration — rather than testing a list of URLs someone remembered to supply.
Chain weaknesses into attack paths
Individually harmless findings are combined the way an attacker combines them. Most real compromises are three small issues in sequence, not one critical vulnerability sitting on its own.
Validate with a working proof-of-concept
Every finding is proven by exploiting it, with reproduction steps attached. This is the difference that matters: signature-matching scanners pattern-match and hand you a queue of maybes to triage, most of which are noise.
Fix, then retest
Findings come to us, not to you. We ship the remediation and the agents re-run against it to confirm the issue is actually closed rather than moved.
Coverage spans the OWASP Top 10 and well past it — injection, SSRF, XXE, remote code execution, broken access control and IDOR, cross-site scripting and request forgery, prototype pollution, and the business-logic and API flaws that generic tooling does not reach.
In front of it
Filtering the noise before it arrives
Testing tells you what could be exploited. It does not stop the constant background traffic every public site receives — credential stuffing, vulnerability probes, scrapers and volumetric junk that arrives whether or not anyone has heard of your business.
That is handled at the edge, in front of the application: bot filtering, rate limiting and DDoS mitigation on the same network the site is served from. It is the always-on layer, and it runs on every site under a Site Care Plan.
Have an application you want tested?
Whether it is a site we built or one you already own, the first conversation is scoping — what you have, what matters, and what a real assessment of it would involve.
