Check Point Harmony Email and Collaboration guide

Check Point Harmony Email and Collaboration is designed to help protect cloud email and collaboration platforms from phishing, malicious attachments, harmful links, business email compromise, account takeover signals, and data leakage. A professional deployment needs more than turning on a product: it requires mail-flow planning, Microsoft 365 or Google Workspace integration, policy tuning, user reporting, quarantine review, identity controls, and measurable response procedures.

Why it matters

Protect email while keeping business communication usable

Email security tools must block threats without interrupting legitimate business communication. The goal is to reduce phishing, malware, impersonation, malicious links, risky attachments, and data exposure while giving IT clear visibility into quarantines, false positives, policy exceptions, and incident response.

A strong Harmony Email and Collaboration program combines vendor controls with Microsoft 365 or Google Workspace settings, identity protection, MFA, mailbox auditing, SPF/DKIM/DMARC alignment, user education, reporting buttons, and a documented escalation workflow.

Practical rule: Do not deploy email security as a silent black box. Document mail-flow dependencies, test with pilot users, tune impersonation and quarantine policies, validate SPF/DKIM/DMARC, train users on reporting, and review false positives and high-risk detections on a recurring schedule.

Review scope

What the email security program should cover

Mail-flow and tenant readiness

Review domains, MX records, connectors, transport rules, accepted domains, API permissions, administrator roles, and backup mail-flow expectations.

Threat prevention policies

Tune phishing, malware, URL, attachment, impersonation, account takeover, and collaboration-file controls based on business risk.

Email authentication

Validate SPF, DKIM, DMARC, third-party senders, alignment, reporting, and the path from monitoring to quarantine or reject.

Quarantine operations

Define who reviews quarantines, how releases are approved, how false positives are handled, and how evidence is retained.

User reporting

Give employees a clear way to report suspicious email and define the triage process for phishing submissions.

Incident response

Document mailbox compromise response, message search and purge, credential reset, token revocation, user notification, and lessons learned.

AreaWhat to verifyQuestions to answerEvidence
Executive impersonationBusiness email compromise can lead to wire fraud, credential theft, payroll diversion, and urgent fake-payment requests.Enable impersonation protection, VIP monitoring, suspicious sender controls, user reporting, and finance verification procedures.Are executives and finance users protected with stricter policies?
Malicious attachmentsAttachments can deliver malware, credential-stealing documents, or payloads hidden in archive formats.Use attachment inspection, sandboxing where available, extension controls, quarantine workflow, and user training.Which attachment types should be blocked, inspected, or released only by approval?
Malicious linksPhishing links may be safe at delivery time and weaponized later.Use URL inspection, time-of-click protection where supported, warning pages, and incident response for clicked links.Can IT trace who received and clicked a dangerous URL?
Third-party sender failureMarketing, billing, CRM, ticketing, and payroll systems can break SPF/DKIM/DMARC alignment if not governed.Maintain a sender inventory, validate DNS records, monitor DMARC reports, and retire unauthorized senders.Which systems are authorized to send as the company domain?
False positivesOverly aggressive policies can delay invoices, customer messages, proposals, and support communications.Define quarantine review cadence, safe release workflow, allow-list governance, and post-release monitoring.Is the release process secure and fast enough for the business?

Step-by-step review

Check Point Harmony Email and Collaboration runbook

1

Assess the current email environment

Inventory domains, mail routing, Microsoft 365 or Google Workspace settings, existing email security tools, third-party senders, VIP users, and incident history.

2

Plan integration and permissions

Document the deployment model, required API permissions, administrator roles, protected mailbox scope, mail-flow dependencies, rollback plan, and support contacts.

3

Pilot protection policies

Start with a controlled group, tune phishing, URL, attachment, impersonation, quarantine, and collaboration controls, and measure false positives and false negatives.

4

Validate authentication and sender governance

Review SPF, DKIM, DMARC, third-party senders, DNS alignment, DMARC reports, and exceptions before moving to stronger enforcement.

5

Operationalize alerts and quarantine

Assign daily review owners, define release approvals, route high-risk detections into tickets, and document message search, purge, and user notification steps.

6

Review trends and improve

Track phishing campaigns, blocked malware, impersonation attempts, false positives, user reports, repeated senders, policy changes, and executive risk reporting.

Common risks

Common email security deployment mistakes

No mail-flow map

Changing email security without a clear routing map can break delivery, scanning, journaling, or third-party sender behavior.

Allow-list sprawl

Broad allow lists can bypass the controls the tool was deployed to enforce.

Weak DMARC governance

SPF and DKIM records alone do not prove that every sender is authorized or aligned with the visible From domain.

Quarantine backlog

Unreviewed quarantine queues create business disruption and hide repeated sender or policy problems.

No user reporting path

Employees may forward suspicious email informally or ignore it if reporting is confusing.

Disconnected incident response

Email detections should connect to mailbox investigation, credential reset, token revocation, and message purge procedures.

FAQ

Check Point Harmony Email and Collaboration FAQ

What should be reviewed before deploying Harmony Email and Collaboration?

Review mail routing, domains, connectors, transport rules, third-party senders, administrator roles, protected mailbox scope, existing email security tools, and rollback options.

Does email security replace SPF, DKIM, and DMARC?

No. Email security controls should complement SPF, DKIM, DMARC, sender governance, user reporting, MFA, mailbox auditing, and incident response.

How should false positives be handled?

Create a documented quarantine review and release process with owner approval, evidence capture, policy tuning, and review of repeated sender patterns.

Which users need stricter email protection?

Executives, finance, payroll, HR, IT administrators, help desk, legal, and users with access to sensitive data or payment approval workflows should receive stricter monitoring and policy controls.

How often should email security policies be reviewed?

Review policies at least monthly and after phishing incidents, mailbox compromise, major domain changes, new third-party senders, or Microsoft 365/Google Workspace configuration changes.
