4C Security



Email is your company’s most critical business communications service. It’s also the number one threat vector for cybersecurity attacks.

Signature-based anti-virus and standard reputation-based anti-spam solutions are no longer the only tools needed to secure email against today’s sophisticated payloads and social engineering tactics. At the same time, compliance requirements are becoming more stringent, and email security best practices are needed to protect your internal and customer data and maintain email archives.

4C Email Protection Services take the complexity and cost of managing your email security and compliance out of the conversation for you.

We provide the advanced integrated technology and resources needed to safeguard the most critical – and the most vulnerable – system in your cybersecurity network while you focus on other important areas of your business.


As email threats evolve and regulations tighten, we adapt our solution to ensure your email continues to be protected and compliant. Leading-edge capabilities include robust data loss prevention; protection from exfiltration, negligence, and insider attacks; and the ability to encrypt emails. Our email continuity and archiving tools enable you to store emails offsite to meet your compliance, discovery, and audit needs.

With 4C Email Protection Services, you can rest assured that your data and communications are secure and compliant – without the burden and cost of staffing, implementing, and maintaining an in-house email security solution.

  • Reduce Exposure and Liability

    We safeguard your email with anti-virus and anti-spam technologies that block malicious software and spam at the gateway.

    Our advanced, cloud-based service stops targeted attacks, spear and longline phishing, and advanced zero-day exploits without relying on anti-virus signatures.

  • Prevent Data Loss

    We help companies of all sizes guard against insider threats with content-aware policies normally reserved for standalone enterprise technology solutions.

  • Add a Layer of Protection

    Our policy-based email encryption makes it easy to send encrypted secure email to anyone, regardless of their email system.

  • Ensure Email Continuity

    Your messages are stored in our secure offsite data center where e-discovery and audit requests can be fulfilled while maintaining business continuity.

  • Automate Archiving

    Automated archiving increases accuracy and efficiency and allows you to easily access stored communications for review, discovery, and audit.

“4C Email Protection Services have been huge for us. The solution has made an immediate impact on improving our security, and with just a four-person IT department, we would not be able to manage all the email protection capabilities, host our Exchange, and focus on the other banking services were it not for 4C managing that for us.”
