Malware only needs one click to do considerable damage to your business. That click is still most often triggered the same way it always has been: a hyperlink to a spoofed login page, a Word or Excel file carrying a malicious macro, unpatched software, or a plain old file attachment paired with a convincing social engineering pitch (“invoice attached,” “please review,” “your delivery couldn't be completed”).
As cyber threats evolve, we face growing email security challenges. Hackers and cyber criminals relentlessly continue to attack businesses as users continue to fall for email scams. That’s why we must continue to be aware of the best practices for securing our email.
Email is still the number one way attackers get into an organization. In 2025, the FBI’s Internet Crime Complaint Center (IC3) logged more than $20.8 billion in reported losses, a 26% jump over the prior year, and business email compromise (BEC) alone accounted for roughly $3 billion of that total. For managed service providers (MSPs), those figures are more than an industry headline. When a client gets hit, the MSP is the one who has to explain what happened, clean up the damage, and answer the hard question of why the defenses did not hold.
Threat actors are continuing their assault on businesses, individuals, and Managed Service Providers (MSPs) this year, and email is still the top vector. As your clients turn to you for secure services, you need to make sure you have the right email security solution in place to protect your customers.
For hackers, it's a numbers game. An estimated 3.4 billion phishing emails are sent every day, but all they need is for one of them to find a willing victim and do damage to your network.
And in 2026, the odds have shifted further in the attacker's favor. Generative AI now writes the majority of phishing emails, producing fluent, personalized, typo-free messages that are far harder to spot than the clumsy scams of a few years ago. Research shows AI-crafted phishing lures achieve dramatically higher click rates than traditional ones, while costing attackers almost nothing to produce at scale.
Needless to say, leaving email security up to end users is probably not a good idea.
G2 just released their Winter 2022 badges, and SecurityGateway™ for Email Servers continues to rank at the top of the Secure Email Gateway Software category.
