Blocking millions of spam and infected emails every month
A global organisation with operations in 30 countries, the Biwater Group was besieged with an exceptional high volume of spam. It also received over 16,000 emails every month that were infected by malware. Redscan provided a cost effective solution to both these challenges, ensuring complete protection for the business.
Internet access and email systems are critical to Biwater’s business. The organisation provides water and wastewater services to millions of people and has delivered projects in more than 90 countries in its 40 year history. Headquartered in the UK, it has provided a piped water supply for 4.2 million inhabitants in Malaysia, constructed sewage treatment works in Abu Dhabi and built one of the largest nano-filtration plants in the world.
Spam presented a massive problem for the company. 80-90% of all emails sent to the company were spam, a total of around one million each month. On top of this, Biwater received around 3,750 emails per week containing malware that could compromise the organisation’s corporate network.
“The volume of spam had started to become unmanageable,” says Lesley Chaddock, IT manager at the Biwater Group. “We were getting regular complaints from employees about the number of spam emails they were having to deal with. It was starting to affect all areas of the business.”
Chaddock turned to Redscan for advice after the company was recommended to her by another organisation. She ran a free trial of Redscan’s Service Delivery Platform (Redscan SDP) and was “completely stunned” at the effectiveness of the service. She says: “It was very straightforward to set up. We used the free trial to get feedback on Redscan SDP from over 700 employees, and the thought of taking it away from them, even after so short a period, was not a pleasant one. The decision to keep it was unanimous.”
The Redscan SDP has been shown to eradicate spam almost entirely — 99.5 per cent, rather than the 95-98 per cent effectiveness of most spam filters. It applies learning from user behaviour and reputation, and analyses an email’s content, reputation and IP address, to change the way spam is detected and treated.
In addition to blocking spam for Biwater, the Redscan SDP is configured to control access to sites that are not business-critical, such as social media platforms and and sites containing adult or inappropriate content. Other web content is scanned by three separate anti-malware solutions from market leaders such has Kaspersky, ClamAV and Comtouch to prevent viruses, Trojans and other malware from entering the network.
Complete peace of mind
Biwater enjoys complete peace-of-mind, knowing that its information security is always up-to-date. With Redscan’s PUSH system, updates are automatically conveyed to each Redscan SDP appliance as soon as they are available.
Instant system improvement
The IT team at Biwater saves time, as it no longer has to manually update its security systems, manage and maintain them. “Our previous product was very time consuming to use,” says Chaddock. “It wasn’t comprehensive enough for our needs and therefore worked out more expensive too.”
Finally, Redscan SDP provides good value for money for Biwater. Chaddock explains: “We were surprised to find that Redscan SDP is much more cost-effective than our previous system — and because Redscan offers unified threat management (UTM), you get more comprehensive protection for less money.”
