About Defensio

European cybersecurity. Built by practitioners.

Our Mission

Serious security visibility is usually priced and packaged for enterprises. We build the Defensio ecosystem so that watching the inside of the network, the external perimeter and the email identity of an organisation is something a mid-sized company can actually run — with a real operations centre behind it when you want one.

Fidem S.r.l.

Based in Verona, Italy. Certified to ISO/IEC 27001, 27017 and 27018, and ISO 9001; Defensio is registered at CSA STAR Level 1. Hands-on SOC experience informs every product decision.

How we secure the products themselves — where data lives, how tenants are separated, how we build — is documented in the Trust Center.

Products born from services

Defensio is not a first guess at security. Fidem has been running security services for organisations across Italy for years — the products industrialise what the team already does every day.

Managed SOC & MDR

Running detection and response for customers is where the SOC product comes from — not the other way round.

Compliance Programmes

NIS2 and GDPR programmes in Italy, from gap analysis to the evidence pack an auditor actually accepts.

Offensive Testing

Vulnerability assessment and penetration testing, feeding the same test catalogue the products use.

Intelligence

OSINT, web reputation and credential breach monitoring for brands and domains.

Digital Forensics

Post-incident analysis and evidence handling on computers and servers.

Secure Development

Application security testing woven into the development cycle, not bolted on after release.

The full service catalogue is on fidemsrl.it (Italian). For international consulting: fidemcybersecurity.com.
