E-mail remains the most common starting point of an attack. If your company runs its own mail server, protection must work on the server, not just on employees’ computers.

Key features

  • Scanning of malicious attachments and links before an e-mail is delivered
  • Protection against phishing and targeted attacks on specific employees
  • Spam filtering
  • E-mail content rules and quarantine

Who it is for

For companies that manage their own mail flow – via a Microsoft Exchange server or a separate mail gateway. If your mail is hosted in the Microsoft 365 cloud, a better fit is “Security for Microsoft 365”.

Why at server level

When scanning happens on the server, a malicious attachment never reaches any employee's mailbox. This matters not only for security but also when you need to prove that an e-mail was stopped – in quarantine you can see what was blocked and when.

What you need to prepare

You will need server administrator access and an agreed installation time – this is usually done outside working hours so that e-mail is not interrupted.

How it is installed

Kaspersky Secure Mail GatewayA separate mail gateway – a virtual or lightweight software appliance placed in front of your mail server. Suitable when you run your own mail system.
Microsoft ExchangeDirect integration into the server – protection works from the gateway right down to mailbox level.

Whatever the deployment method, e-mails are checked in several layers: signatures, heuristics and behavioural analysis. Sender authenticity is verified using SPF, DKIM, DMARC and domain matching, and phishing attempts hidden in QR codes and AI-generated e-mails are recognised. Attachments can be sanitised using CDR – dangerous content is removed from the document while the file itself remains usable. Password-protected archives are scanned too.

Questions about the product

Why is no price shown?The price of this solution depends on the number of workstations and the chosen term, so it is calculated separately for each company. We prepare a quote on the same business day.
Can I try it before buying?Yes. We arrange a trial version so that you can test the solution in your own environment.
Do you issue a VAT invoice?Yes, for every order. Payment by bank transfer and against a pro forma invoice is also available – payment methods.
Will e-mails be delayed?No. Scanning takes place while the e-mail is in transit and is measured in fractions of a second – employees will not notice it.
What if the filter holds back an e-mail I need?Blocked e-mails go to quarantine, where the administrator can review and restore them. The sender can be added to the list of trusted senders.
