Enterprise Anti-Spam Solutions for Houston Businesses

Our hardware-based spam firewall is an integrated hardware and spam protection solution designed to protect your email server from:

  • Spam
  • Viruses

  • Phishing
  • Spyware attacks

Our spam firewall protection leverages 12 comprehensive defense layers to provide industry-leading spam defense capabilities for any email server within large corporate or small business environments in the Houston, TX area.

The #1 Spam Firewall

As the #1 most widely used spam filtering solution and winner of numerous industry honors, leading organizations around the world continue to trust Hardware Spam Firewalls for complete protection against spam and its resource demanding consequences.

The Spam Firewall is compatible with all email servers and can fit into nearly any corporate or small business environment. It is used by small organizations with as few as 10 employees and large organizations with as many as 200,000 employees. Contact CITOC today to find out how our spam protection solutions can help your Houston business or organization, too.

A single Spam Firewall handles up to 30,000 active email users. Multiple units can be clustered together for even greater capacity and high availability.

Barracuda Spam Firewall Protection

The Barracuda Spam Firewall architecture optimizes the processing of each email to maximize performance and process millions of messages per day. Unlike software solutions, our spam firewall reduces the load placed on the email server by off-loading both spam and virus filtering.

In addition, all our spam firewall models include essential outbound filtering techniques, including:

  • Attachment scanning
  • Virus filtering
  • Rate controls
  • Encryption

These features help Houston businesses to ensure that all outgoing email is legitimate and virus-free.

At CITOC, we design and build spam protection products not only for their power and ease of use but also for their affordability. With NO per user license fees, our Spam Firewall is the most affordable enterprise-class spam protection solution available.
