The problem

Products ship. Websites rot.The next owner is usually guessing.

Usual way

A scanner PDF after the testing window has already closed.

A site nobody will touch, with unclear domain and hosting owners.

A finding the developer cannot replay on the real path.

Care that depends on whoever last remembered the passwords.

How GK Data works

Named targets and written authorization before the work starts.

Behavior reproduced by hand, written so an owner can act.

Repair with a record of accounts, DNS, hosting, and recovery.

Monthly care on a defined rhythm, not a mystery.

Two paths

Pick the problem in front of you.

Security review and website care are different jobs. The first screen should say so.

01 / Application security

The product can be abused.

Founder-led review of web applications, APIs, mobile products, identity, and business logic. I map the surface, reproduce exploitable behavior, document the path, and verify the fix.

  • Heavy recon, then a deep dive on in-scope assets
  • Evidence a developer can act on
  • Retest after the fix

02 / Website repair & care

The website is already failing.

Broken WordPress, failed updates, missing backups, or a site nobody is comfortable touching. I diagnose, repair, document ownership, and keep it on a monthly website care subscription from Blaine, MN.

  • Rescue, recovery, and ownership cleanup
  • Updates, backups, forms, and malware checks
  • WordPress, static HTML, or Next.js that should not rot

How it works

How the work is done

  1. 01

    Scope

    Named targets, roles, and exclusions in writing. No scanner queue. No weeks of theatre before the first real path.

  2. 02

    Proof

    Behavior reproduced by hand, with the affected boundary and practical impact intact so an owner can act.

  3. 03

    Retest

    Reported paths checked after remediation, including nearby bypasses.

If the surface is already clear

Start on the part of the product that carries the risk.

Each security review is scoped around the system, the users, and the decision that needs to be made. Website repair stays on its own path.

Selected writing

Public research and practical notes.

Read the work before deciding whether the approach is a fit.

Start a conversation

Tell me what you need to test, repair, or make dependable.

I will review the context, ask for only what is needed to scope the work, and be direct if it is not the right fit.
