CyberVuln LLC

Most pentest reports fail at the one job they have.

Not finding vulnerabilities. Getting them fixed.

You've probably seen it: a 120-page PDF, raw scanner output, CVSS scores with no context, and a "remediation" section that just says "sanitize user input."

Then your developers spend days figuring out what the report actually means, while the vulnerability stays open.

At CyberVuln LLC, we write every report with one question in mind:
Can a developer read this and fix it today?

So every finding comes with:
→ What's wrong, in plain language
→ Why it matters to your business, not just a severity label
→ Exact steps to reproduce it
→ A clear, specific fix for your stack
→ How to verify the fix actually worked

No dedicated security team? That's fine. Our reports are built so your dev team can own remediation from day one.

And if something's still unclear, you talk directly to the person who found it.

A pentest is only worth something if it gets fixed.

We just delivered a large-scale pe*******on test for a client that genuinely cares about security.

They test every year. On schedule. No shortcuts.

And the report still came back heavy, with multiple critical and high-severity issues.
Not because they're careless. Because once a year simply can't keep up with how fast modern products change.

Every sprint adds new endpoints, integrations, dependencies, and access paths. A pentest captures one moment. Everything you ship after it is untested until next year.

The teams that stay ahead do three things:

→ Monitor their external attack surface continuously

→ Test around major releases, not just the calendar

→ Treat security as a cycle, not an annual event

Caring about security is the first step. Testing at the speed you ship is the second.

How often is your product tested?

*******onTesting

Your demo environment is production with fewer buttons.

We started an assessment with no credentials and no signup page. The only way in was a locked-down demo.

Three findings later, we had stored JavaScript executing in the browsers of users who opened that record.

The path:
→ Guessable route exposed the signup page the demo was supposed to hide
→ A boolean in the server response — not the server itself — decided who saw admin functionality
→ Admin write access led to an unsanitized field, and stored XSS

Attack chains don't show up in a scanner report. They show up when someone asks "and then what?" after the first finding.

Is the lock on the door, or just painted on the wall?

One of our testers looked at a SaaS platform that limited free organizations to a single user. The “Invite User” button was greyed out, with a tidy “upgrade for more seats” prompt next to it.

The catch: that limit lived entirely in the browser.

The invite endpoint — /api/v1/users-invite — required a valid login, but never checked the org’s plan or seat count. Replay the request directly (Burp, curl, anything) and the server happily returned 200 and sent the invite. A free-tier account could add unlimited members and walk straight past the paid upsell.

No payload. No injection. No exploit chain. Just an HTTP request the backend forgot to validate.

That’s exactly why business-logic bugs slip through: teams test that the button is disabled, not that the endpoint rejects the call. A disabled button is UI — never a security control.

No system is 100% secure. That is not a disclaimer — it is the starting point of the job.

Code ships. New subdomains go live. Vendors change configurations. Infrastructure evolves every day. None of that cares whether you passed an audit last quarter.

Security isn't something you finish. It's something you continuously maintain.

During the first half of 2026, our team notified more than 500 organizations of security exposures affecting their external attack surfaces.

Twenty of those organizations chose to continue working with CyberVuln LLC across external attack surface management, pe*******on testing, and continuous security monitoring.

We're extending the same opportunity to a limited number of companies.

The first five companies to apply will receive a free external attack surface assessment.

No contracts. No commitments. The findings are yours to keep.
