We at 3SL take network security and organisational security very seriously. We believe that keeping our network secure and protecting ourselves and our clients from attack is vital to maintaining our credibility and enhancing client confidence.

Your privacy and security are just as important to us as ours are. We are dedicated to maintaining the highest levels of security and dependability in our infrastructure, systems and processes at ALL times.

We have undertaken an intense security review and changed our policies accordingly. This in addition to a regular, on-going assessment and review procedure.

We are continuously reviewing our policies in this regard and future changes will be implemented without advance notice.

We will take any action we deem necessary to protect our network infrastructure and our client's confidence in our ability to operate a secure, reliable service, free from attacks or infestation.

After the latest review we have implemented the following security policies.

Spam E-Mail and Virus Protection:

The following has been implemented:

• A dedicated security team involved in an on-going review of all policies relating to all aspects of site and network security.

• This new newsletter distribution e-mail address has been protected so that ONLY internal staff can send to it.

• We do not accept email from open relays.

• All incoming e-mails into the threesl.com e-mail addresses are now automatically scanned and those that are spam are automatically identified as such.

• When a spam e-mail is deleted, our mail server automatically sends a 'no such address' bounce e-mail back to the sender - in the hope that this may cause the spammer to stop sending us such e-mails.

• If the e-mail does not get rejected, then the content of the e-mail is automatically scanned for viruses. This happens inside the e-mail server, before the e-mail ever reaches it's recipient.

• Our e-mail server will now automatically reject any incoming e-mail that has an attachment of any (but not limited to) the following file types:

  • COM,

  • BAT,

  • SCR,

  • PIF,

  • LNK,

  • VBS,

  • JS,

  • CMD,

  • VBS,

  • ZIP.EXE,

  • DOC.EXE,

  • JPG.EXE,

  • TXT.EXE

• If a virus is found in the e-mail, it is automatically rejected.

• On the subject of firewalls, the company has had a firewall up and running ever since we first started hosting www.threesl.com on our own server.

Your Privacy:

We have adopted a set of information management guidelines that serve as the basis for our customer and General user relationships. These have been developed to comply with the Data Protection Act 1998 and the Privacy and Electronic Communications (EC Directive) Regulations 2003. We take note of advice published from time to time by the Information Commissioner. Accordingly, guidelines are subject to change and any such changes to our privacy policy will be posted on this page without notification.
