Spam Filtering

What exactly is “spam”?

It is estimated that at least 80 per cent of all global email traffic is spam – worthless information sent in bulk to an indiscriminate set of recipients without their consent. The purpose of spam is always to make money in some way.

At best these types of emails are a nuisance and time consuming to delete, but they may also have the intention of spreading viruses or spyware.

How can spam be stopped?

Spam filters will always help in the fight against spam. These anti-spam software programmes analyse and assess incoming messages and block 97 per cent of junk email before it reaches you, your staff or your IT systems. We can provide tailored spam protection to reduce the amount of spam your organisation receives through our partnerships with leading security solutions providers.

A spam filter will manage and screen all inbound and outbound email traffic, protecting your organisation from email-based threats and data leaks. As a complete email management solution, a spam filter will allow you to encrypt messages and leverage the cloud to spool email if mail servers become unavailable.

Anti-Virus Software

What are computer viruses?

The term “computer virus” covers all unwanted intruders that can access your IT network with the intent of harming it. This includes worms, trojan horses and spyware, which can all inflict significant damage and disruption such as deleting files, accessing personal data or using your computer to attack other connected devices.

How do they access devices?

Anyone opening an infected email; accidentally clicking on an unsafe link via a webpage; or downloading an infected file can introduce a virus to you network. Therefore, all your devices are potentially vulnerable to attack.

Can they be prevented?

Having robust and effective anti-virus software is essential if you want to prevent viruses attacking your network. With hackers and criminals continually searching and finding new ways to exploit weaknesses in your systems, keeping up to date with anti-virus software is your best defence. 

We offer a cloud-or server-based, centrally-controlled, anti-virus system to protect, update and manage all your connected devices. This proactive approach ensures your antivirus – whether for Windows or other platforms – is kept up to date. We provide antivirus protection for both individual PCs and servers.

Firewalls

What is a firewall?

Firewalls are systems designed to prevent unauthorised access to or from a private network. They can be software or hardware, or a combination of both.

Why are they used?

All businesses have banking transactions and other sensitive documents that may be of interest to others and could be exploited by computer hackers. Firewalls may be used to prevent these unauthorised users from connecting to your private network, particularly an intranet.

How do they help?

All messages through your intranet should pass through a firewall – it examines each one and blocks any that do not meet specified security criteria. By using secure authentication certificates and logins, a firewall can also allow remote access to a private network, meaning employees may access documents when away from the workplace.

We will help you create the ideal firewall configuration of hardware and software. This will ensure your business is protected from hackers, while allowing access to authorised parties.
