Email Security | Protect Your Most Important Communication Channel

Secure corporate mail against phishing, spam and data leakage

E-mail is the most common attack vector for organisations — over 90% of incidents start with a click on a crafted message. Email security is not a single anti-spam plug-in; it is a set of filtering layers, attachment analysis, anti-spoofing authentication (SPF, DKIM, DMARC) and correspondence encryption. Virtline selects and deploys solutions matched to organisational size, the mail server in use and regulatory requirements — NIS2, DORA, GDPR and ISO 27001.

We work with vendors who have an established market position — GFI Software, TitanHQ, Fortra (formerly ClearSwift). Every project begins with an analysis of mail flow, a DNS record configuration audit and a review of existing policies. We then propose on-premise or cloud solutions, integrate them with Microsoft 365, Google Workspace or a private mail server, and after deployment maintain continuous monitoring of filter effectiveness.

Benefits of email security deployment

 Fewer ransomware incidents — cutting off the primary attack vector reduces the risk of data encryption and costly downtime.

 Protection from financial fraud — detection of CEO impersonation attempts, invoice account number changes and classic BEC attacks.

 Regulatory compliance — support for GDPR, NIS2, DORA and ISO 27001 requirements on communication security and personal data protection.

 Recovered team time — employees stop wasting minutes on spam and false notifications; IT receives fewer support tickets.

 Better domain reputation — correctly configured SPF, DKIM and DMARC reduce the risk of outbound messages landing in recipients’ spam folders.

 Threat visibility — reports on blocked phishing and malware help the security team respond faster to new patterns.

 Secure document exchange — encryption allows contracts, proposals and personal data to be transmitted without risk of interception.

Email security solutions from Virtline’s portfolio

We select tools to match company size and the existing mail stack. In most projects we reach for proven solutions that consistently rank at the top of analyst market reviews.

1. GFI MailEssentials — a multilayer anti-spam and antivirus filter with 14 detection engines. Works well in mid-sized organisations with their own Exchange or Postfix server, allowing precise policy control for different user groups.

2. SpamTitan Plus Cloud by TitanHQ — a cloud filter with real-time URL analysis, attachment sandboxing and an admin interface. Deploys quickly without any changes to mail infrastructure.

3. ClearSwift Secure Email Gateway (Fortra) — a mail gateway combining content filtering with Deep Content Inspection of attachments. Works both on-premise and in Microsoft 365 or Google Workspace environments.

4. PhishTitan by TitanHQ — a dedicated anti-phishing layer for Microsoft 365; integrates with the native filter and blocks attacks that slip through Exchange Online Protection.

5. EncryptTitan by TitanHQ — e-mail encryption compliant with GDPR and HIPAA requirements, with a recipient portal for people who do not have their own encryption key. Enables secure document exchange with external clients.

What threats does email security address?

Modern e-mail attacks rarely rely on classic spam anymore. Cybercriminals combine social engineering with technical tricks and domain typosquatting. Email security addresses the full spectrum of contemporary threats:

• classic phishing and spear-phishing targeting a specific employee
• ransomware delivered in attachments or via links to malicious sites
• Business Email Compromise (BEC) and fraudulent payment instructions
• domain spoofing — messages impersonating a corporate e-mail address
• spam campaigns overloading the mail server and user filters
• malware hidden in Office document macros and archive files
• supply chain attacks via compromised accounts of trusted partners
• data leakage through accidental sending to the wrong recipient

Each of these threats requires a different protection layer — from sender reputation and content analysis through attachment inspection to DLP policies and encryption. In each project we scope the solution to address the real risks of your organisation, not to purchase unnecessary modules.
