The traditional “trust everything inside the network” model stopped working with the mass shift to remote work. According to Microsoft, 94% of companies with Zero Trust reported fewer security incidents.
Three pillars of Zero Trust
Verify every request, least privilege access, and assume breach. In practice: MFA for everyone, Conditional Access, network microsegmentation, encryption, SIEM monitoring.
Step-by-step implementation
- Step 1: MFA for all accounts — blocks 99.9% of identity attacks
- Step 2: Conditional Access — policies based on device, location, risk
- Step 3: EDR — endpoint protection
- Step 4: Network microsegmentation
- Step 5: SIEM + SOAR — monitoring and automated response
How SL Global Service solves this
SGS engineers conduct security audits and build Zero Trust on Microsoft Entra ID + Cisco Duo for MFA, Microsoft Sentinel for monitoring with Cisco Firepower and CrowdStrike integration. Typical project — 2–4 months, 60–80% attack surface reduction.
Start with MFA and Conditional Access — greatest impact with minimal investment.
“The security perimeter no longer exists — when employees work from home and coworking spaces, the only approach is to verify every request regardless of source.”
