Advanced threat protection

Sophos Time-of-Click protection blocks malicious email URLs, protecting your users from stealthy, delayed, spear phishing attacks. Every URL, in every email, is secured. Every time an email link is clicked, on any device, its reputation is checked against our cloud-hosted Sophos SXL database. No client software is required, speeding implementation and reducing user disruption. Our new Sophos Sandstorm* enhances targeted attack protection, visibility, and analysis. Sandstorm complements our advanced antivirus scanning engine to quickly and accurately detect, block, and respond to evasive threats using powerful cloud-based, next-generation sandbox technology.

Quick and easy data protection compliance

Our wizard-based DLP rules and policy-based encryption makes email data protection simple— preventing costly data-loss incidents. Using our built-in lexicon of hundreds of sensitive data types, you can quickly and easily build DLP policies for users or groups. Protect your information by blocking messages containing sensitive data or by encrypting them before they leave the network gateway.


EasyLock the solution creates an encrypted area on your preferred location. If you have private files or confidential data and you want to avoid somebody else having access, you can protect them by password-based military-strength AES 256bits CBC-mode encryption with EasyLock. Eliminate the threat in case a USB flash drive or portable hard drive is lost or stolen and ensure the data shared on cloud services is safe. Being a cross-platform solution, it works on Windows and macOS in order to secure confidential data.

Used with Endpoint Protector or My Endpoint Protector, it can turn any USB stick into a TrustedDevice Level 1.

SPX Encryption—encryption you can use

Our patent-pending simple SPX Encryption is transparent, simple and requires no changes to user workflow. It doesn’t require clumsy and expensive key management or additional software. SPX Encryption simply encapsulates the email content and attachments into a secure encrypted PDF that can’t be hacked or cracked. But it allows users to view their encrypted email anywhere: in their preferred email client, in their webmail or on their mobile device.

Stamp out snowshoe spam and suspicious email content

Our sophisticated email filtering protects users from the latest snowshoe spam, identity theft, password scams and more by looking for suspicious content, attachments or URLs. Support for Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) ensures spam and phishing attacks attempting to spoof legitimate sender domains are blocked. You can also block unwanted content and be sure our proven antivirus scanning is catching the latest threats.
