39D Privacy and Customer Data Retention Policy

This privacy policy is here to help you understand what information we collect and how we use it. This policy only describes how 39D treats your information, not how other organisations treat your information. If you are using 39D in a workplace or on a device or account issued to you by your employer or another organisation, that company or organisation likely has its own policies regarding storage, access, modification, deletion, and retention of communications and content which may apply to your use of any 39D. Content that would otherwise be considered private to you or to a limited group of people may, in some cases, be accessible by your account owner or administrator. Please check with your employer or account administrator about the policies it has in place regarding your communications.

Fair and Lawful Processing

Many of the current regulations and processes 39D adhere to require a person to be named as the subscriber for the service. An example of this may be a telephone number or broadband service that cannot be anonymous or unnamed or without an address for installation or emergency services purposes. Person(s) wishing to continue with services should, therefore, offer an alternative to allow 39D Limited to continue being able to continue providing existing services.

GRU Cyber Attack Allegations – Protecting Your Business from Cybercrime

Last week, the National Cyber Security Centre (NCSC) discovered and exposed several cyber-attacks that were conducted by the Russian military intelligence service, the GRU. Britain – along with its allies Australia and New Zealand, have accused the GRU of being responsible for many attacks over the past couple of years.

Even with the latest instalments in cyber security, large Government agencies are becoming victims of cyber crime. Any organisation can be victimised by cyber crime, making it vital for your business to maximise its Cyber Security capabilities, and to help prevent an attack from occurring.

Here are four ways you can protect your business from Cyber crime

Installing anti-virus and anti-malware solutions on your devices will minimise the risk of an attack and will protect your business against the latest threats, including ransomware, malware, hackers and so on.

Download the latest updates on OS and applications

As well as installing the latest anti-virus software for your PCs, it is important that you download the latest updates for your operating system, and for every application you use, as soon as they come available. With the end of Windows 7 OS just around the corner, you will need to migrate to the latest Windows OS, as security will no longer be released, making you more vulnerable to newly developed malware.

Ensure That Your Passwords Are Secure

Whilst this may seem like an obvious way to prevent a breach, it is one of easiest ways for hackers to access your data. Passwords provide the first line of defence to your PC and if a password is simple enough, hackers will take a guess and most likely gain access and control of your data.

It is vital that your employees all have strong and secure passwords, to ensure that hackers cannot intrude your devices. As a simple rule, ensure that your employees have at least 12 characters in their password, 1 capital letter, 1 number and 1 symbol.

Undertake Staff Awareness Training

It’s highly important that your staff are aware of cyber security, and their responsibilities in preventing cybercrime. By carrying out cyber security awareness training, you will ensure that your team are fully aware of cybercrime and understand the consequences of their actions. This will reduce the chance of a cyber-attack and will mean they follow the correct procedures.

We are Cyber Essential Certified, and provide training and awareness programs to businesses that want to educate their team and make them aware of cybercrime. This program will provide your team with the tools and knowledge to prevent a cyber-attack from happening.

39 Support provides a comprehensive range of Cyber Security services that will help avoid the possibility of a cyber-attack. We’ll ensure that your data is 100% secure and that you are compliant with the latest regulatory requirements, including GDPR and ISO27001.
