What is Retruster?

Retruster is an add-on for Microsoft Outlook that checks incoming emails for signs of ransomware, phishing and fraud. Set up takes less than 5 minutes.

How does Retruster work?

When a user gets an email that shows signs of ransomware, phishing or fraud, they are automatically warned within Outlook and given the reasons behind the warning.

How does Retruster safeguard my data?

Retruster complies with the highest standards of data protection, including being Microsoft approved and GDPR compliant.

What about my other anti-virus and anti-spam products?

Anti-virus and anti-spam products don't stop phishing and fraudulent emails, which is why a purpose-built tool like Retruster is needed. Retruster works just fine with other solutions in place.
