The two-layer model

Email filtering and ITDR solve different parts of the attack

Email security filters malicious content and can flag email-account anomalies. Petra extends that foundation with dedicated ITDR for tenant-wide Microsoft 365 identity activity, containment, and forensics after authentication. Together, the controls cover more of the attack path while keeping their different roles—and ITECS response ownership—clear.

Layer 1 · Prevention

Check Point

Managed email filtering

Check Point Email Security—formerly Harmony Email & Collaboration—inspects email and applies protection before the inbox, at click time, and after delivery. Its email-security scope also includes compromised-account anomaly detection.

  • Phishing, impersonation, and BEC prevention
  • Malware, attachment, and malicious-link inspection
  • Inbound, internal, and outbound email controls
  • Quarantine, post-delivery action, and policy reporting
Layer 2 · Detection + response

Petra Security

Managed Microsoft 365 ITDR

Petra looks for evidence of successful identity compromise and helps contain and reconstruct attacker activity across Microsoft 365.

  • Session hijacking, token theft, and AiTM detection
  • Account, session, application, and persistence response
  • Microsoft 365 attack-impact and blast-radius analysis
  • Root-cause timelines and client-ready incident reports

Petra does not replace email security. Check Point protects message content and includes email-account takeover signals. Petra adds dedicated, tenant-wide Microsoft 365 ITDR, attack-impact analysis, forensics, and remediation. ITECS manages the handoff and overlap between those controls. See Petra’s product distinction.

Microsoft’s 2025 Digital Defense Report release noted that identity attacks rose 32% in the first half of 2025, more than 97% were large-scale password attacks, and 80% of incidents its security teams investigated involved data theft or leakage. Read the Microsoft report.

Layer 1 · Check Point

Check Point stops threats before and after delivery

Check Point Email Security uses API-based inspection to evaluate inbound, internal, and outgoing messages for phishing, business email compromise, malicious links, malware, data leakage, and email-account takeover signals. ITECS deploys the platform, aligns policies to your risk, manages operational workflows, and keeps protection tuned as threats and business needs change.

Phishing, BEC, and account protection

Analyze sender and correspondence behavior, message context, and Microsoft account activity to detect impersonation, BEC, and signs of a compromised email account.

Malware and attachment defense

Inspect files for known and zero-day threats, with sandboxing and content sanitization available according to the selected package.

Link and click-time protection

Evaluate destinations when messages arrive and when users click, helping stop malicious sites that change after delivery.

Policy and data protection

Apply quarantine, outbound inspection, and data-loss controls that reflect licensing, business workflows, and compliance requirements.

What ITECS manages

The operating layer behind the platform

Software alone does not decide your policy, investigate edge cases, or communicate with your team. ITECS turns the platform into a managed control with defined owners.

  • Tenant and mail-flow assessment
  • API connection and permission validation
  • Policy, quarantine, and exception design
  • Alert and user-report workflows
  • Ongoing tuning and operational review
  • Leadership and compliance reporting

Review Check Point’s official Email Security platform guide for current capabilities. Check Point renamed Harmony Email & Collaboration to Check Point Email Security in March 2026. See the official naming update. Features vary by plan, so ITECS confirms the licensed scope during assessment.

Layer 2 · Petra Security

Petra expands identity visibility after sign-in

Petra Security monitors Microsoft 365 activity for evidence that an identity is already under attacker control. Its behavioral detections, containment actions, and forensic timelines help ITECS move from a suspicious sign-in to a documented response across Entra ID, Exchange Online, SharePoint, OneDrive, Teams, and registered applications.

Behavioral compromise detection

Look beyond location alone to identify session hijacking, token theft, AiTM activity, suspicious app consent, and attacker behavior using valid credentials.

Identity containment

Support rapid session revocation, account locking, related-phish retraction, and removal of malicious persistence within the approved response scope.

Attack-impact analysis

Show which email, files, applications, and identity settings an attacker accessed or changed across the Microsoft 365 tenant.

Forensic reporting

Build a root-cause timeline with observed activity, impact, and remediation evidence for leadership, compliance, insurance, and incident review.

Historical visibility

6 months

Petra Scan can review up to six months of available Microsoft 365 audit history for past and active compromise evidence.

A faster path to incident facts

Petra documents root cause, attacker actions, affected resources, and response steps. Official scan guidance describes a typical 24–48-hour turnaround after onboarding and permission validation.

Lookback depth depends on audit data Microsoft was already recording; historical logs cannot be created retroactively. Containment actions and response hours depend on the service scope approved for your organization.

Attack-to-response view

See how email-centric protection and tenant-wide ITDR work together

Attackers do not follow product boundaries, so the operating model cannot either. This view shows which layer acts at each stage, where responsibilities overlap, and how ITECS connects prevention, identity response, and communication into one service path without pretending that one tool can cover every attack.

The ITECS service

A managed program with clear response ownership

For Dallas-area and nationwide clients, ITECS owns the day-to-day work that turns vendor software into an operating security control: discovery, deployment, policy design, alert handling, escalation, containment coordination, reporting, and improvement. Response authority, service hours, integrations, and licensed features are documented before go-live so your team knows what happens next.

Scope the layers to the environment. The assessment does not assume a mandatory bundle: ITECS can recommend Check Point, Petra, or both based on your email platform, Microsoft 365 exposure, existing controls, and response needs. Final licensing and managed-service scope are confirmed in the proposal.

  1. 01

    Assess

    Map mail flow, Microsoft 365 identity controls, licensing, privileged roles, notification paths, and current incident ownership.

  2. 02

    Deploy

    Connect the approved platforms, validate permissions, establish policies, document exclusions, and test escalation paths before broad rollout.

  3. 03

    Operate

    Review alerts, tune controls, coordinate containment, manage approved response actions, and keep client stakeholders informed.

  4. 04

    Improve

    Use incident timelines, tenant reports, and operating trends to recommend policy, training, identity, and broader security improvements.

Defense in depth

Connect inbox and identity signals to the rest of your security program

ITECS can align this service with your broader cybersecurity program, including endpoint detection and response, security awareness training, penetration testing, and readiness work for HIPAA or CMMC.

Common questions

Managed email security and ITDR FAQ

Most buyers want to know where filtering ends, when ITDR begins, and who acts during an incident. These answers explain platform coverage, deployment, historical analysis, containment, and service scope so you can compare the approach against your current Microsoft 365 and email security controls.

Do we need both email filtering and ITDR?

Not every environment needs both on day one. Check Point and Petra can be assessed and scoped as separate layers based on platform, existing controls, and risk. Microsoft 365 organizations often benefit from combining email protection with post-authentication ITDR; the final recommendation and licensing are documented in your proposal.

Does Petra Security replace Check Point Email Security?

No. Petra Security is Microsoft 365 Identity Threat Detection and Response, not an email content filter. Check Point protects email and collaboration content and also includes email-account anomaly and takeover signals. Petra adds dedicated tenant-wide identity detection, attack-impact analysis, forensics, and response after authentication.

Which platforms does this service protect?

Check Point Email Security supports Microsoft 365 and Gmail, with collaboration and data-protection coverage determined by the selected package. Petra Security is specific to Microsoft 365 and monitors relevant activity across Entra ID, Exchange Online, SharePoint, OneDrive, Teams, applications, and related audit logs.

What can happen when Petra detects an identity compromise?

Based on your approved response scope, containment can include revoking sessions, locking an account, retracting related phishing messages, and removing persistence such as malicious inbox rules, unauthorized applications, device registrations, or connectors. ITECS documents escalation, authorization, communication, and follow-through before go-live.

Can Petra find attacks that happened before deployment?

Petra Scan can analyze up to six months of Microsoft 365 audit history for evidence of past and active compromise. The available lookback depends on logs Microsoft was already recording, because historical audit data cannot be generated retroactively. Official guidance describes a typical 24–48-hour scan turnaround after onboarding.

What does ITECS manage in the combined service?

ITECS assesses the environment, deploys the approved platforms, designs policies and escalation paths, validates alerts, coordinates authorized containment, manages tuning, and delivers operational or incident reporting. Licensed features, response hours, integrations, and decision authority are confirmed in the service scope for each client.
