Advanced Email Security for Microsoft 365 & Google Workspace
Email is still the most common way cyber attacks begin. Phishing, invoice fraud, and account takeover don’t rely on obvious malware – they rely on messages that look genuine. Avanan (Check Point Harmony Email & Collaboration) adds an advanced layer of protection to Microsoft 365 and Google Workspace, helping identify and stop email-based threats that native security can miss.
Optimising IT offers a 14-day free Avanan trial, so you can see what’s really getting through your current defences – without disrupting email delivery or your users!
What Is Avanan (Harmony Email & Collaboration)?
Avanan integrates directly with Microsoft 365 and Google Workspace using secure APIs. There’s no mail rerouting and no impact on performance.
It focuses on modern, high-risk email threats, including phishing, impersonation, malicious links and attachments, account takeover, and internal phishing from compromised accounts.
Protection also extends beyond the inbox into collaboration tools such as Teams, SharePoint, OneDrive, and Google Drive (requires relevant Microsoft & Avanan License levels).
Why Native Email Security Isn’t Enough
Built-in security does a good job with basic threats, but modern attacks are designed to blend in. Many use trusted senders, compromised accounts, or convincing language that passes basic filtering.
Avanan adds behavioural and contextual analysis, helping identify threats that look legitimate – and responding when risk changes after delivery.
What You’ll See During the 14-Day Trial
Avanan runs quietly alongside Microsoft 365 and Google Workspace, analysing real activity.
During the trial, you’ll gain visibility into:
- Phishing and impersonation emails bypassing existing controls
- Invoice fraud and payment-related attacks
- Malicious links and attachments
- Internal phishing from compromised accounts
- Threats appearing in Teams, SharePoint, and OneDrive
- Shadow IT usage
Protection Against BEC and Account Takeover
Avanan uses behavioural analysis to identify compromised accounts and suspicious activity, helping stop:
- CEO and finance team impersonation
- Supplier payment redirection
- Lateral phishing within your organisation
This is critical for reducing the financial and reputational impact of any email-based attacks.
Data Loss Prevention
Avanan also includes data protection capabilities to help reduce accidental or malicious data leakage.
This is particularly valuable for organisations handling sensitive or regulated information, such as legal, financial, healthcare, and professional services firms.
Who Is Avanan Right For?
Avanan is for organisations that:
- Use Microsoft 365 or Google Workspace for email and collaboration
- Handle payments, invoices, or sensitive data via email
- Are regularly targeted by phishing or impersonation attacks
- Want stronger protection without added disruption
