In short

What is Security Monitoring and Consulting?

Microsoft 365 security consulting and monitoring covers assessing and hardening identity, email, endpoints, collaboration and data protection in Microsoft 365, then continuously detecting and responding to threats. TechTiera uses Microsoft Defender XDR, Microsoft Sentinel, Entra ID Protection and Purview, with security posture tracked through Microsoft Secure Score and independent baselines.

Security Monitoring & Consulting

Security assessment and hardening

We benchmark your tenant against Microsoft Secure Score, Zero Trust guidance and CISA SCuBA secure configuration baselines, then fix findings in risk order. Typical high-impact fixes:

  • Block legacy authentication and enforce phishing-resistant MFA for administrators
  • Require compliant or hybrid-joined devices for access to sensitive apps
  • Enable token protection and sign-in risk policies to counter token theft and adversary-in-the-middle phishing
  • Restrict user consent to applications and review OAuth grants
  • Turn on Defender for Office 365 preset security policies and move DMARC to enforcement
  • Remove standing admin roles in favor of just-in-time access

Microsoft Sentinel correlates these with firewall, server and SaaS logs in the unified Defender portal. We tune analytics rules to cut noise, automate containment with playbooks (disable user, revoke sessions, isolate device) and manage ingestion costs with the right log tiers.

Security Monitoring & Consulting

Incident response and reporting

When an alert is real, analysts investigate, contain and communicate under agreed response times, then deliver a root-cause report with the configuration changes that prevent recurrence. Monthly reports cover incidents, Secure Score trend, open risks and recommended improvements.

Compliance alignment

Questions, answered

Security Monitoring & Consulting FAQs

What is Microsoft Secure Score?

Microsoft Secure Score measures how many recommended security controls are enabled in your Microsoft 365 tenant. It is a useful progress indicator, but we pair it with independent baselines because a high score does not guarantee every risk is covered.

Do we need Microsoft Sentinel if we have Defender XDR?

Defender XDR covers Microsoft 365 workloads well. Sentinel adds non-Microsoft log sources, longer retention, custom analytics and automation, which most organizations need for complete coverage and compliance.

How do you protect against business email compromise?

Phishing-resistant MFA, Conditional Access, token protection, Defender for Office 365 anti-phishing and impersonation protection, DMARC enforcement, alerts on suspicious inbox rules and user training together close most BEC paths.

Which Microsoft 365 license do we need for advanced security?

Microsoft 365 E5 or the E5 Security add-on includes Defender XDR, Entra ID P2 and advanced Purview capabilities. Business Premium covers many controls for organizations up to 300 users. We map requirements to the least expensive license that meets them.

Can you monitor our environment 24x7?

Yes. TechTiera provides round-the-clock monitoring and response using Defender XDR and Sentinel, with escalation paths and response times agreed in the service contract.

How quickly can you improve our security posture?

Most high-risk gaps, such as legacy authentication, missing MFA and standing admin access, can be closed in the first 30 days of an engagement.
