Top 10 Anti-Phishing Software

Phishing increased by 600% worldwide in 2020, making it crucial to adopt anti-phishing software.

Anti-phishing software is defined as a software platform or a set of software services that identifies malicious inbound messages impersonating a trusted entity or attempting to obtain trust via social engineering, enables remedial actions, and empowers users to create blacklists and whitelists for message filtering. This article discusses what anti-phishing software is, what criteria to consider before investing, and the top anti-phishing software in 2021. 

What Is an Anti-Phishing Software?

Anti-phishing software is a software platform or a set of software services that identifies malicious inbound messages impersonating a trusted entity or attempting to obtain trust via social engineering, enables remedial actions, and empowers users to create blacklists and whitelists for message filtering. It is an essential part of email security, helping organizations stave off the entry of malware, virus, ransomware, or even zero payload attacks via email. 

In recent years, phishing has emerged as a massive threat for both enterprise and consumer-grade users. A 2020 Verizon investigation noted that the use of malware and trojans has declined while attackers have started favoring more efficient tactics like phishing and credential thefts. It exploits user ignorance, misplaced trust, and natural human psychology to deceive users and obtain funds or monetizable data. 

The Proofpoint report also found that just 49% of U.S. employees were able to correctly define phishing. Globally, nearly 4 in 10 employees didn’t know what phishing was. This is a worrying figure, given that over 80% of employees are likely to check or respond to personal email on their work devices. Companies not only need a stellar anti-phishing solution to safeguard communication on their corporate channels, but they must also invest in user awareness training to prevent risks arising from shadow IT/device usage outside of the corporate network. 

Some of the risks you could be incurring without anti-phishing mechanisms in place are: 

  • Loss of data: Employees share confidential information with a malicious entity, mistaking them for a colleague or any other trusted party. 
  • Credential theft: Employees click on a malicious link or download a malicious file that logs keystrokes or obtains login credentials by spoofing the actual account provider.
  • Ransomware infection: Employees click on a file attachment or download a malicious file from a URL mentioned in an email, only to find that their data is now encrypted until they pay a ransom.
  • Wire transfer fraud: Employees believe the email sender legitimately and urgently requires a specific sum and wire-transfers the amount directly. 

An anti-phishing software can detect emails with these or other malicious intent to take the appropriate action. 

Key Must-Have Features in Anti-Phishing Software

Anti-phishing software should offer the following must-have capabilities: 

Essential Features of Anti-Phishing Software

Phishing protection should be a top priority for companies in 2021, given that the pandemic caused a 600% spike in phishing attacks last year.
