Penetration testing for your website and AI tools before attackers find the gaps.

Webiyo tests business websites the way an attacker would. With your written authorization, we map your site, find its vulnerabilities, and send a coordinated team of AI agents to exploit them. Every finding is then verified by a person and delivered with a clear plan to fix it.

Built for live business websites, customer logins, booking and checkout flows, APIs and AI chat features. Every engagement starts with a free scoping call and a fixed quote. Nothing is tested until you sign off.

  • Written authorization first
  • Agents run on our own machines
  • Every finding verified by a person
  • OWASP-alignedTested against the OWASP Top 10 for web applications and for LLM applications.
  • Exploit-provenWe confirm a vulnerability can be used, and show you the evidence.
  • Human-verifiedA person reviews every finding. No unverified scanner output in your report.
  • Retest includedOnce you've fixed the issues, we test again to confirm they're closed.
What is AI penetration testing

Attacker-grade testing, sped up by AI and checked by people

A penetration test is an authorized, simulated attack on your website. It goes past a vulnerability scan: instead of listing what might be wrong, it shows what an attacker could do with it.

Attackers already use AI to find and exploit weak sites at scale. We use the same approach to defend you. After an automated mapping phase charts your site and flags candidate weaknesses, a coordinated team of AI agents works each lead the way a human attacker would: testing logins, sending crafted input to forms, probing access between accounts, and chaining small issues into larger ones.

Speed comes from the agents. Judgment comes from our team. Every result is reviewed, reproduced and rated by a person before it reaches you, so your report contains confirmed risk, not noise.

What we test

Every way into your business online

Scope is agreed before testing starts. Most engagements cover some or all of these.

  • Web applications

    Forms, booking and quote flows, checkout and file uploads, tested for injection, cross-site scripting, request forgery and business logic flaws.

  • Authentication and access

    Logins, password resets and sessions. Whether one user can reach another user's data, or an ordinary account can reach admin functions.

  • APIs

    The endpoints behind your app, booking system or integrations, tested for broken authorization, data exposure and input handling.

  • AI chatbots and assistants

    Prompt injection, jailbreaks, leaking of private data or system instructions, and unsafe actions by assistants connected to your tools.

  • WordPress and CMS

    Core, plugin and theme versions against published vulnerabilities, exposed admin pages, user enumeration and leftover files.

  • External attack surface

    DNS, TLS, security headers and email authentication (SPF, DKIM, DMARC), plus any services exposed to the internet.

Engagements

Two ways to work with us

Every engagement is scoped on a free call and quoted at a fixed price before any work starts.

External, non-intrusive

Security Assessment

A review of everything visible from the internet, with no login and no active exploitation. A good first step for brochure and WordPress sites.

  • External attack surface: DNS, TLS, headers and email authentication
  • CMS, plugin and theme versions against known vulnerabilities
  • Exposed files, admin and backup pages
  • Report with a severity rating and fix for each finding

Full engagement

Penetration Test

The full assessment, then AI-led exploitation with manual verification. For sites with logins, booking, payments, APIs or AI chat features.

  • Everything in the Security Assessment
  • Unauthenticated and authenticated testing, using a test account you provide
  • Web application, API and AI chatbot testing as scoped
  • Proof of exploitation for every confirmed finding
  • Prioritized remediation plan and a retest after fixes
Methodology

How an engagement runs

Six phases, each with a clear owner. Testing never starts before phase one is signed off.

  1. 1

    Scoping and authorization

    A free call to agree targets, test accounts and limits. You confirm ownership and sign written authorization, then receive a fixed quote.

  2. 2

    Reconnaissance

    We map your site, its technology and everything it exposes to the internet.

  3. 3

    Vulnerability analysis

    Automated and AI-assisted analysis flags candidate weaknesses for the agents to pursue.

  4. 4

    Exploitation

    AI agents attempt to exploit each lead, without changing or deleting data, inside the agreed window.

  5. 5

    Verification and reporting

    A person reproduces each result, rates its severity and writes the fix. Then we walk you through the report.

  6. 6

    Remediation and retest

    You fix the issues, or we quote to fix them. We retest to confirm each one is closed.

The report

Findings you can act on

Your report opens with a plain English summary for the business owner: what's at risk, how serious it is, and what to fix first. Behind it sits the technical detail your developer needs.

  • Executive summary with an overall risk rating
  • Each finding with its location, severity and impact
  • Step-by-step reproduction and evidence
  • Specific remediation guidance, ranked by priority
  • Retest results once fixes are in place
Finding 01 of 03Example
High

Customer data redacted. We prove access without retaining it.
Impact
Anyone with the address can read customer names and phone numbers, and alter or cancel bookings.
Remediation
Require authentication on the admin route and exclude it from search indexing. Low effort.

Rules of engagement

Built to test safely

Every engagement follows the same controls, agreed in writing before testing starts.

  1. 01

    Written authorization

    We test only systems their verified owner has authorized in writing.

  2. 02

    Defined scope

    Targets, accounts and limits are listed up front. Anything outside scope is never touched.

  3. 03

    Backups confirmed

    A current backup is confirmed before the first test request.

  4. 04

    Staging first

    Where you have a staging copy of your site, testing starts there.

  5. 05

    Non-destructive

    We prove a vulnerability without changing or deleting your data, and never run denial of service.

  6. 06

    Local agents

    Our agents run on our own machines. Your data is never sent to an outside AI service.

  7. 07

    Stop on anomaly

    If anything looks wrong during testing, we pause and contact you before continuing.

  8. 08

    Human verification

    AI finds and exploits. A person verifies every finding before it reaches your report.

Out of scope in every engagement: live payment abuse, data deletion, accessing live customer accounts, third-party systems, denial of service, internal networks, phishing and social engineering.

What a penetration test can't promise

A penetration test shows how your site holds up against a determined attacker on the day it's tested. It lowers your risk. It can't make a site unhackable, and we won't claim it does.

It isn't a compliance certification or a legal audit. It won't change your rankings or AI visibility; that's a separate Webiyo service. And if we confirm no vulnerabilities, your report says so and documents everything we tested.

Common questions

Something we didn't cover? Email info@webiyo.tech.

How much does a penetration test cost?

It depends on the size of your site and what's in scope. Every engagement is scoped on a free call and quoted at a fixed price before any work starts, so you know the cost up front.

What's the difference between a vulnerability scan and a penetration test?

A scan lists weaknesses that might exist. A penetration test, with your authorization, tries to exploit them and shows you what an attacker could do, with evidence.

Will testing break my site?

Testing is non-destructive. A backup is confirmed before we start, and we use a staging copy first where you have one. You may see extra traffic and a few test form entries during the agreed window.

Where does my data go?

Nowhere outside Webiyo. Our AI agents run locally on our own machines, so nothing from your site is sent to an outside AI service. Any customer data we encounter is redacted in the report.

Can you test our AI chatbot?

Yes. We test AI chat features and assistants for prompt injection, jailbreaks, data leakage and unsafe actions, as part of a penetration test scope.

Do you need our login details?

Only for authenticated testing, and only a dedicated test account you create for us. We never ask for your own admin credentials.

How long does it take?

Most engagements are reported within about two weeks of scope sign-off. Your quote confirms the timeline.

What if you don't find anything?

Your report says so and documents everything we tested. We don't invent findings.

Is this a compliance certification?

No. A penetration test can support compliance work, but it doesn't certify you for any standard.

Can you test a site we don't own?

No. We only test for the verified owner, with written authorization.
