mnemonic is the only Nordic-headquartered provider recognised among the representative vendors in Gartner’s 2026 Market Guide for Cybersecurity Incident Response Retainer Services.

The Gartner report highlights how incident response retainers have become a core component of cyber resilience programmes, driven by growing regulatory complexity and leadership demands for better cyber resilience.
