About this category

This category holds tools that secure client email. They primarily stop malicious emails and filter spam, though many also provide continuity and encryption services. We list 109 products here. These solutions are essential for protecting your clients from a constant barrage of phishing attempts and malware.

When evaluating these tools, look at their specific filtering methods. Some products, like Vade Remote Browser Isolation, use AI to analyze email content and isolate potential threats in real time within a browser sandbox. Others, such as N-able's DNS Filtering, block access to malicious domains at a network layer, preventing users from even reaching dangerous sites. Consider how each approach fits your clients' risk profiles.

Most of these tools integrate with your core PSA platforms, ensuring smooth operations. You will find products that connect with ConnectWise PSA, Autotask PSA, and Halo PSA for automated ticketing and billing. Many also integrate directly with Microsoft 365, simplifying user management and deployment for your clients.

Complete Protect™ from IRONSCALES is one option. BLOKWORX offers both Self-Managed and Fully Managed Email Security, each with a public API for custom integrations. OpenText Cybersecurity provides Email Threat Protection. N-able's Mail Assure uses AI to refine its filtering and improve threat detection. Mailprotector's SafeSend helps prevent accidental data leaks by prompting users before sending sensitive information.

Email security needed a new trust foundation, so we built it. Traditional approaches that make trust decisions based on message sources or content analysis aren’t enough anymore. They’re too easily spoofed and manipulated, especially with the rise of AI. That’s why Shield’s zero trust foundation is built around your unique communication patterns. By automatically learning who you interact with and how you handle messages, Shield creates a trust network of verified contacts. Our adaptive intelligence (AI) turns this behavioral data into personalized protection, delivering only the email you want with no extra effort required.

Scalable Email Security to counter phishing and data loss. With more people turning to their devices for work, it’s no surprise that email is still the communication mode of choice in business. Yet cyber threats such as phishing attacks and Business Email Compromise (BEC) have never been more prevalent. One study concluded that a cyberattack occurs on average every 39 seconds and according to Verizon’s Data Breach Investigation Report, 25% of data breaches are tracked back to phishing. Considering the average cost of a data breach is over $3.8 million per business, resulting in $6 trillion in cybercrime worldwide, it’s no wonder global enterprises are demanding comprehensive, scalable email security to effectively prevent these types of attacks. S/MIME (or Secure/Multipurpose Internet Mail Extension) is the most ubiquitous email security protocol available today. S/MIME certificates are backed by verified identity information allowing users to digitally sign their emails, thus identifying them as the legitimate sender and differentiating from spoofed emails. They also make it possible for users to fully encrypt emails to protect all contents – whether they’re in-transit or at rest. S/MIME encryption can only be decrypted by the intended recipient using PKI, thus preventing data loss or leaks. GlobalSign empowers customers and partners to easily adopt S/MIME by providing certificate deployment and management services – with solutions that scale to accommodate businesses of any size. The solution offers full certificate lifecycle management and comprehensive scalable automation. Our S/MIME offering is also completely tamper evident supporting non-repudiation, thus alerting users to any changes to email content after it has been sent.
