Stormshield

Stormshield Endpoint Security Evolution is built by a company that already belongs to this directory's most demanding audience: Stormshield is a wholly-owned subsidiary of Airbus Defence and Space Cyber Programmes, and its endpoint agent holds a CSPN qualification from ANSSI, the French national cybersecurity agency, plus a Producto Cualificado approval from Spain's CCN-LINCE.

Those are external checks TEHTRIS's ANSSI-qualified components share but that ESET, Bitdefender and G DATA do not publish, which makes Stormshield the second sovereignty-grade option in this category, aimed at the same French public-sector and critical-infrastructure buyers TEHTRIS serves.

Where SES Evolution differs from TEHTRIS is emphasis: signatureless behavioural detection, device control and an agent architecture hardened against direct attacks on itself, rather than a platform reaching into mobile and containers.

Stormshield's own privacy notice says data is processed mostly within the EEA, with standard contractual clauses covering the rest. Pricing is quoted rather than published, there is no trial listed, and — like TEHTRIS — the partner network thins out fast outside France; a buyer without a sovereignty requirement will find ESET or Bitdefender easier to simply buy and run.

What Stormshield does well

• ANSSI CSPN qualification and CCN-LINCE (Spain) approval
• Signatureless behavioural detection built to survive attacks on the agent itself
• Backed by Airbus Defence and Space
• Device control included to reduce the attack surface
• Data processing mostly within the EEA

Where Stormshield falls short

• Quoted pricing only, no published price list
• No trial listed
• Thin partner network outside France, like TEHTRIS

Standout feature. A second sovereignty-grade option next to TEHTRIS: ANSSI's CSPN and Spain's CCN-LINCE have both signed off on the same agent.
