Ideal Customer
- Link11's sweet spot is mid-market to large enterprises, particularly those with 500+ employees or high-value digital assets for whom online availability is mission-critical.
- Its target audience includes European enterprises with strict GDPR and compliance requirements, high-traffic e-commerce and finance firms where even seconds of downtime translate to major revenue loss, and organizations managing hybrid- or multi-cloud environments that need a unified security layer.
Key Differentiators
- Link11's primary differentiator is its patented, fully automated AI- and machine learning-based DDoS protection that achieves zero-touch mitigation—detecting and blocking attacks in seconds (0–10 seconds per vector) without human intervention, eliminating manual filtering latency and human error.
- Unlike threshold-based competitors, Link11 uses ML to establish traffic baselines and neutralize zero-day and unknown attack vectors before they impact services.
Industries Served
- Link11 primarily serves financial services (banking, insurance, finance), e-commerce and retail, media and entertainment, telecommunications, logistics, energy and utilities, online gaming, and the public sector.
- According to PeerSpot user data, financial services firms represent its largest customer segment, followed by communications service providers, construction, outsourcing, and education.

Partnerships
- Link11 operates a formal channel partner program targeting managed security service providers (MSSPs), system integrators, hosts, resellers, and security consulting partners, following a 'Channel First' strategy that treats partners as a central growth vehicle.
- Notable technology and infrastructure partnerships include BSO (global connectivity provider), which supplies network capacity to support Link11's AI-powered DDoS mitigation.
Company Size & Ownership
- Link11 was founded in 2005 by co-founders Jens-Philipp Jung (CEO) and Karsten Desler (CTO/Managing Director) and has approximately 111–115 employees as of 2026, spread across three continents.
- Estimated annual revenue ranges from approximately $21M (per ZoomInfo and RocketReach) to $25–50M (per LeadIQ), reflecting its growth following two major acquisitions.
Compliance & Certifications
- Link11 holds ISO/IEC 27001 certification for information security management, SOC 2 Type 2 attestation, and achieved PCI-DSS Level 1 certification (the highest tier) in August 2025, applied uniformly across its entire product portfolio.
- It is also certified under Germany's BSI C5 2020 (Cloud Computing Compliance Catalogue) and is compliant with GDPR and NIS2 (the EU's updated cybersecurity directive), completing its NIS2 registration as a qualifying digital service provider.
