Ransomware and extortion
An entry point to connected systems can be exploited to exfiltrate data, block services, or encrypt files.
Charter Nine · Website security
We detect vulnerabilities. And fix them.
Charter Nine examines your website, performs the agreed security repairs, and tests if they work. We do this as much as possible behind the scenes: your design, content, and recognizable appearance are preserved. If a visible adjustment is needed, we discuss it with you in advance.
Your website remains your website. We strengthen the security behind your existing design.
What is at stake?
A vulnerability can affect more than one web page.
Your website connects visitors with data, accounts, forms, payments, and sometimes other business systems. A full audit helps strengthen those access routes before an incident.
Data theft and fraud
Customer data, requests, accounts, and payment flows are valuable. Strong access control helps prevent misuse and manipulation.
Downtime and revenue loss
A disrupted website can halt forms, orders, and customer portals at the moment customers need them.
Abuse of your reputation
A taken-over website can distribute false content, phishing, or malicious redirects under your trusted domain name.
Our services
From determination to a controlled result
You receive confirmed findings, clear priorities, and a concrete remediation path. Remediation takes place within the agreed assignment and every correction is retested.
Investigate
We assess the full fixed framework. Only checks for demonstrably absent functions are recorded as not applicable, with a documented reason.
Security auditRemediate
We carry out the agreed security fixes ourselves. If you prefer to work with your own developer, we guide the repair and check the result.
Remediation processCertify
After a successful retest, C9 Verified makes your current control status visible to visitors.

We check this
Every website goes through the same fixed control domains. This way you know in advance which technical and organizational components will be addressed.
The investigation only starts after you have accepted the proposal and the price.
- Fixed control domains
- 9
- Concrete checkpoints
- 83
- Scope, architecture and safe preparation
- Infrastructure, configuration and browser security
- Identity, sessions and access permissions
- Input, APIs and file handling
- Privacy and data protection
- Secrets and cryptography
- Dependencies and software supply chain
- Business logic and resistance to abuse
- Detection, incidents and recovery
From technical risk to business reliability
Prevent a technical problem from escalating into a business incident.
Vulnerabilities in access control, forms, external services, or data processing can lead to downtime, data theft, fraud, recovery costs, and loss of trust.
Targeted investigation and demonstrable remediation strengthen your daily operations and support the security obligations under the GDPR.

Frequently asked questions
Clear answers before you decide.
What does Charter Nine check besides HTTPS?
We also evaluate code, access rights, accounts, forms, API connections, data processing, dependencies, and server configuration. This gives you a much broader view of actual web security.
Is the check suitable for a website built with AI?
Yes. We assess the concrete end result: the code, configuration, data flows, dependencies, and production environment. The construction method used does not change that thorough approach.
What the process concretely delivers
You receive confirmed findings, clear priorities, and a remediation plan and execution within the agreed assignment. Every correction is retested. After approval, your domain receives the publicly verifiable C9 Verified certificate.
Will my current design be preserved?
Yes. Your layout, content, and brand style form the starting point. Improvements are made as much as possible behind the scenes, and visible choices are discussed beforehand.
What does C9 Verified mean?
C9 Verified is issued exclusively by Charter Nine after investigation, remediation of all confirmed findings, and a successful retest. The certificate is valid for one year and publicly verifiable.
How can visitors verify the certificate?
The badge links to a unique verification page. Visitors can also enter the exact domain name in the certificate register and see the current status, assessment date, validity period and the full fixed audit framework.
