Email Security Tools Are A Necessity
When most of us hear the term "email security," we think about things like password security and questionable mail attachments. Unfortunately, even the most secure email provider out there doesn't offer protection against every mail threat that comes your way. This is why everyone needs the best email security software they can afford — it keeps your personal data and your inbox safe from hackers and other cyber attacks.
Best Email Security Solutions
Since email security best practices are important to nearly every individual with an email address, there are hundreds of options for mailbox security. However, not every company offers the same quality tools, so it’s important to find the best solutions based on your budget and needs instead of waiting until you have been pwned to act.
1. Avanan
Avanan Email Security offers protection against viruses, phishing, malware, data loss, and account compromises. Avanan also analyzes each user’s email history, which allows it to quickly detect mail fraud and user impersonations, which can be a serious issue if undetected. The tool offers protection for nearly any mail service provider, plus other collaborative apps like Google Drive, Slack, and more.

Avanan’s pricing starts out at just $3/month per user for their basic plan, and their Complete Security package starts at $6/month per user. However, enterprise customers with more than 500 mail users will need to obtain a custom quote directly from Avanan.
While Avanan is one of the more sophisticated email security solutions out there, it is also one of the most complicated to operate. For this reason, you may need a very tech-savvy person on your team to help with setup and regular use.
2. Barracuda Email Security
Barracuda is a cloud-based security software that protects users against malware, phishing, denial-of-service attacks, and spam. Barracuda also offers encryption and mail attachment protection, meaning you don't have to worry about an email data breach.

Barracuda offers three different plan options: advanced, premium, and premium plus. Unfortunately, the company does not publicly provide their pricing information, which makes it hard to compare apples to apples with other top email security software providers.
3. N-able Mail Assure
N-able Mail Assure offers protection against viruses, spam, malware, ransomware, phishing, and nearly any other type of email threat. The system offers protection both for incoming and outgoing emails, and features like the system’s authentication techniques help keep everyone’s inbox safe. N-able Mail Assure also offers integration with Office365 and unlimited mail archiving.

Although N-able offers a free email security software trial without any required payment methods, they don’t offer up their pricing without getting a direct quote from their sales team. This can be a turn off to some customers, but it really just depends on what you’re looking for in terms of mail security.
4. Proofpoint
Proofpoint Email Protection offers a robust amount of mail security, including antivirus and antispam protection. The company includes data loss prevention and outbound filtering as well, not to mention other email management features. Furthermore, Proofpoint offers tools like email encryption, imposter mail protection, and report features.

Proofpoint protection starts out at $2.95/month per user for the base plan and goes up to $6.95/month per user for their highest level tier. However, the company also offers a free trial of their product, which is great for users who like to test drive a new software before buying it.
However, Proofpoint doesn't offer mail attachment protection at any tier, which is something that some of its competitors do offer.
5. SpamTitan
SpamTitan is an advanced email security software that's specifically designed for businesses and other large organizations. It offers protection against malware, phishing, denial-of-service attacks, spam, and more. Additionally, SpamTitan includes custom filtering tools, data leak prevention, and email encryption.

Although pricing for SpamTitan starts out at a hefty $37.50/month, it's features are well worth the premium. This is especially true for organizations that use Office365 since it easily integrates with this mail service provider.
About the only thing SpamTitan doesn’t offer is phone or web-based tech support, which is a bit disappointing considering that mail attacks require fast action.
