Attachments checked before anyone opens them
Every file that arrives by email is scanned before it enters your company. If it's a virus or it's dangerous, it's held back and never reaches your inbox.
Two barriers for every attachment
Recognizing a known virus isn't enough. That's why we combine a leading antivirus with the blocking of files that are dangerous by their very nature.
ClamAV on every attachment
We scan every attached file with ClamAV, a widely used antivirus with a signature database that is constantly updated.
Blocking dangerous files
Executables, scripts and risky macros are blocked even if the virus isn't recognized. That also protects you from the ones that are still new.
We look inside compressed files too
Attackers hide the virus inside a ZIP to throw you off. PostCleaner opens compressed files and checks what's inside, just like with a normal attachment.
- Ransomware: programs that encrypt your files and demand a ransom often arrive as an attachment or a link.
- Phishing with attachments: fake invoices or notices with a file that steals your data when opened.
- Fake trusted senders: the attachment is checked even if the email looks like it's from a customer.
It stays out
The dangerous file is held back before it reaches anyone on your team.
Quarantine and a notice, no scares
It's detected
The antivirus or the dangerous-file blocking flags the message before it reaches your server.
It goes to quarantine
The message is stored separately, safe. It reaches no mailbox and stays available for 14 days.
We let you know
You see it in the daily report and in message tracking: what arrived, when, and what was done with it.
The best defense is the filter plus common sense
No system covers everything. These simple habits strengthen your team's protection.
Distrust the unexpected
If you weren't expecting an attachment, ask the sender through another channel before opening it.
Keep everything up to date
An up-to-date system, browser and programs close the doors many attacks use.
Make backups
A copy kept off the network is the best insurance against ransomware.
Don't let an attachment cost you a headache
Turn on PostCleaner's antivirus on your domain and let dangerous files stay out.
