Encryption: protecting your data even when something goes wrong.

Encryption makes your data unreadable to anyone who does not have the right key to unlock it. If a laptop is lost, if an email is intercepted, or if a hard drive is removed from a stolen device, encryption is what stands between an attacker and your actual data.

Encryption service

Encryption makes your data unreadable to anyone who does not have the right key to unlock it. If a laptop is lost, if an email is intercepted, if a hard drive is removed from a stolen device, encryption is what stands between an attacker and your actual data.

We configure and manage encryption as a standard part of every managed support contract, not as a separate product you need to research and buy.

Full-disk encryption

Every laptop and PC in your business should have its hard drive encrypted. If a device is lost or stolen, full-disk encryption means the data on it is unreadable, even if someone removes the drive and tries to access it directly on another machine.

We enforce BitLocker on Windows devices and FileVault on macOS, with encryption keys held centrally so that access can always be recovered by an administrator if needed — for example if a user forgets their password or a device needs to be unlocked for legitimate business reasons.

This is one of the simplest and most effective security controls available, it requires no ongoing action from your staff, and it is a requirement for both GDPR compliance and Cyber Essentials certification.

Email encryption

For businesses that handle sensitive information by email — financial details, personal data, legal documents, client confidential information — we configure email encryption so that those messages are protected in transit between sender and recipient.

Encryption can be applied automatically based on the content of a message or the recipient, or triggered manually by the sender when they know a message contains something sensitive. Either way, it works within your existing Microsoft 365 or Google Workspace environment without requiring a separate system.

Why this matters

A lost laptop without encryption is a data breach. A lost laptop with encryption is an inconvenience. The difference is whether the data on the device can actually be read by whoever finds it.

The same applies to email. An unencrypted email containing sensitive data, if intercepted, exposes that data in plain text. An encrypted email remains unreadable without the correct key, even if it is intercepted in transit.

Who needs this

Encryption matters for every business, but it is particularly important if your business handles personal data subject to GDPR, financial information, legal or confidential client documents, or any information that would cause real harm if it became public. If you are working towards Cyber Essentials certification, encryption is one of the technical controls that will be assessed.

Part of your managed support contract

Full-disk encryption and email encryption are included for Network Fish managed support clients as part of the security stack we configure and manage. There is no separate product to buy, no encryption keys for you to manage yourself, and no additional setup required from your side.

One monthly fee. One number to call.

Frequently asked questions

What is full-disk encryption and why does my business need it?

Full-disk encryption protects the entire contents of a device hard drive by making it unreadable without the correct encryption key. If a laptop is lost or stolen, full-disk encryption prevents the data on it from being read by whoever finds it, even if they remove the hard drive and try to access it on another machine. It is a requirement for GDPR compliance for any business handling personal data, and a Cyber Essentials technical control. We enforce BitLocker on Windows and FileVault on macOS as standard for managed support clients.

Does encryption slow down my computer?

No, modern full-disk encryption has minimal performance impact on current hardware. Both BitLocker and FileVault are designed to run in the background without any noticeable effect on day-to-day use.

What happens if a user forgets their password on an encrypted device?

Encryption keys are held centrally by Network Fish, so access can always be recovered. If a user forgets their password or a device needs to be unlocked for a legitimate business reason, we can assist with recovery without the data being lost or permanently inaccessible.

What is email encryption and when do I need it?

Email encryption protects the content of a message so that it cannot be read by anyone who intercepts it in transit — only the intended recipient can decrypt and read it. It is particularly important for emails containing financial information, personal data, legal documents, or any other sensitive content. We configure email encryption within your existing Microsoft 365 or Google Workspace environment, either applied automatically based on content or recipient, or triggered manually by the sender.

Is encryption required for Cyber Essentials certification?

Encryption supports several of the Cyber Essentials technical controls, particularly around secure configuration and data protection. While Cyber Essentials does not mandate a specific encryption standard, having full-disk encryption in place on all devices is widely regarded as essential good practice and will be assessed as part of your overall security posture during certification.

Is encryption included in a Network Fish managed support contract?

Yes. Full-disk encryption and email encryption are included as standard for Network Fish managed support clients, configured and managed as part of your overall security stack. There is no separate product to purchase or manage yourself.
