Our mission

To help companies (VSEs, SMEs, ETIs), local authorities and associations reduce their vulnerability to email-borne cyber-attacks.

Free IT teams from the mental burden of detecting and filtering known and unknown email-borne threats.

Specialized in email security, our solutions provide advanced protection against email-borne attack threats and guarantee the security of electronic communications.

Our mission is to detect and block targeted attacks, malware, phishing, ransomware and other forms of cyberthreats that can be propagated via email.

We offer cutting-edge security solutions based on artificial intelligence (AI) and machine learning. These solutions enable us to analyze incoming and outgoing emails in real time, identify attack signals and take action to block potential threats.

In addition to security, we also focus on the operational continuity of email communications. We aim to ensure the availability and resilience of messaging systems in the event of failure or disruption, so that organizations can continue to communicate effectively.

In short, our mission is to offer comprehensive and effective protection against email-related threats, using advanced technologies to detect, block and prevent attacks, and helping users to strengthen their security and vigilance against cyberthreats.

Altospam aims to create a safer digital environment for businesses, and to ensure business continuity without interruption due to email attacks.
