Team PresidioSec
Incident response and cyber resilience for SMEs
2026-04-01
Why the problem is not purely technical
In the first hours of a cyber incident, the most common blocker is not lack of tooling but lack of a decision path. Who decides? Who communicates? What gets isolated? What gets documented?
PresidioSec exists to reduce that ambiguity. The priority is not to do everything, but to do the few things that materially change the outcome.
The three windows to control
First 30 minutes: isolate, capture initial evidence and activate the crisis team.
First hour: inventory impacted systems, verify backups and assess regulatory impact.
First 24 hours: containment, internal communication, notification preparation and possible escalation to external support.
