Simplify's Take
What believers are saying
- Advens launched SOC Triad on February 25, 2026, targeting digital-sovereignty buyers.
- June 2026 CERT bulletins cite actively exploited vulnerabilities, strengthening demand for response services.
- The 2025-2026 threat report emphasizes AI-driven attacks, boosting demand for advisory and managed defense.
What critics are saying
- HarfangLab and Gatewatcher partnerships expose Advens to vendor dependence if either weakens.
- CybelAngel’s January 2026 alliance intensifies competition in external attack-surface security.
- If mySOC loses differentiation, sovereign European MDR buyers migrate to larger platforms by 2027.
What makes ADVENS unique
