Our consultants hold security accreditations from Cisco, Microsoft and Checkpoint, as well as the world renowned Certified Information Systems Security Professional (CISSP), the vendor independent security certification covering all ten domains of information systems security.

Deploying an effective IT security infrastructure is a continuous task. It is important to ensure that security policy is properly implemented to detect an incident and respond with the correct, measured methodology. Managing security consists of a constant threat, vulnerability and risk analysis being applied to the security infrastructure.

Polar Computer Communications is able to offer the complete range of security services from initial audit and vulnerability assessment through to deploying and managing security infrastructure such as:

• IDS
  
• Firewalls
  
• VPN Devices
  
• Authentication
  
• Penetration testing
  

• Compliance with statutory and industry related regulations
  
• Enhanced client confidence through an effective security regime
  
• Protection from embarrassing exposure or loss of data
  
• Skilled professionals monitoring your security status 24x7
  
• Ability to effectively prosecute individuals through an effective security policy
  
• Reducing the number of vulnerabilities reduces the chance of someone attempting to access your sensitive data.

VPN Virtual Private Networking

Using a low cost shared public resource such as the Internet to carry private data using VPN is becoming a popular concept.

It may appear to be a simple financial decision, however the proposed solution frequently does not match the requirements of the network. Polar has helped several clients migrate to a more appropriate technology when the deficiencies of VPN have become apparent following installation in an inappropriate environment.

In some cases, VPN implementations can actually work out more expensive than a private network, due to the need for a firewall as well as a router.

It is a popular myth that VPN over ADSL is an effective solution universally. The very nature of ADSL means that the high speed flow of data is in one direction (from the Internet), therefore provisioning ADSL at a central or hub location restricts the upstream traffic to a trickle, compared to the high speeds quoted in the downstream direction.
Often it is not possible to obtain more than 128Kb/s (the same as ISDN) in the upstream direction.

It is also not well publicised that the use of a PC, with a VPN client installed to connect to your network, increases the vulnerability of your network unless strong authentication techniques are employed.

As a certified VPN and Security specialist Polar can help deploy a secure, effective VPN solution where the technology is appropriate and meets the network requirements.
