Goes beyond traditional approaches

Web Application
Firewall

Block common attack vectors such as SQL injections, XSS, and CSRF around the clock.
Protect against OWASP Top 10, Form manipulation, exploits, and effectively secure sessions and cookies.
Benefit from Zero-Day exploit defense, using real-time threat to detect and blocking new and evolving threats.

Your shield against known and unknown attacks

Instead of relying solely on traditional methods, such as IP blocking or signature detection, WAF provides you with an intelligent protection concept: Suspicious content is analyzed in real time, access is controlled in a targeted manner, and dangerous entries are blocked immediately. Whether account takeover attempts, zero-day exploits, or malicious payloads — you can rest assured that your applications are effectively protected at all times.

In Link11, we have found a provider that meets all our requirements. In addition to technical aspects, Link11 stands out because it is a German company. Many of our customers decide to outsource services to Germany, so this is a good fit.

When onboarding with Link11, it must be emphasized that the contact and response speed were always very good and extremely helpful at all times.

With Link11, we now have technologies in place that provide the best possible protection—all without any latency delays.

Comprehensive protection in real time – flexible, adaptive, and precise against threats

Comprehensive threat protection

Comprehensively protect web applications against the OWASP Top 10—the world's most critical security risks—and a wide range of other common attack vectors. A powerful combination of precise signature detection and intelligent heuristic analysis reliably identifies threats and blocks them in real time.

Ready to use

Thanks to preconfigured rules and signatures, you get immediate protection without having to invest valuable time in complex setup or lengthy fine-tuning. The solution is ready to use right out of the box and defends against threats in real time, allowing you to focus on your core business.

Adaptive security

Regular signature updates ensure your protection is cutting edge. New threats and attack methods are continuously analyzed, and defense mechanisms are automatically adjusted. This means your security infrastructure is constantly evolving—without any extra effort on your part.

Flexible policy control

With granular policies (ACLs) and customizable rules, administrators have full control over security policies. This allows you to tailor protection precisely to the requirements of individual applications, from selectively allowing trusted sources to blocking suspicious activity.

Zero-day protection

Targeted application whitelisting and precise validation stop malicious traffic before signatures are even available. This proactive strategy protects your applications against completely new, unknown attack methods and ensures constant availability.

Verifiable false positives

The sophisticated detection logic accurately distinguishes between real threats and normal user behavior. This reduces false alarms without affecting legitimate users. The result: maximum security without compromising the user-friendliness or performance of your services.

Link11 Web Application Firewall

Web Application Firewall (WAF) –
Stop threats before they cause damage

We continuously monitor the internet for new vulnerabilities and threats. If a new threat is detected, your platform is automatically updated with the appropriate protective measures—quickly, reliably, and without any action on your part.

Zero-day exploits are successfully blocked because only traffic that complies with precisely defined, finely tuned application rules is allowed. This makes it virtually impossible for attackers to inject malicious code.

Maintain full control over your data traffic. With our unique access control technology, you can specify which countries, cities, networks, companies, anonymization services, or cloud and data center environments are allowed or blocked.

Using state-of-the-art biometric analysis, Link11 detects early on when attackers are scouting your system—for example, through penetration tests, reverse engineering, or automated scans. These activities are automatically stopped before any damage can be done, keeping your applications and data fully protected—without you having to lift a finger.

Discover all the benefits with Link11

Put your trust in a European company that complies with all relevant data protection and compliance requirements under EU law.
