The Top 9 Anti Impersonation And Spoofing Solutions

90% of all data breaches stem from impersonation or spoofing based phishing attacks. Explore the best solutions for tackling these threats.

The Top 9 Anti Impersonation And Spoofing Solutions include:

Email phishing continues to be one of the biggest threats to the security for companies worldwide. Phishing activities – ransomware in particular – are among the top threats to both public and private sectors. This is due both to its prevalence and ability to hit hard when successful and means that safeguarding against phishing attacks is now a crucial component when it comes to maintaining a strong security posture.

Impersonation and spoofing are the two main forms of phishing attacks aimed at employees. While the two terms seem interchangeable, they refer to very similar but fundamentally different methods of attack. If it tricks a computer, it’s a spoofing attack. If it tricks a human, it’s an impersonation attack.

To aid in the search for a solution to help tackle this threat we have put together a list of our top picks for an anti-impersonation and spoofing solution. These choices each offer their own distinct features and capabilities and have been examined based on our own technical assessments and customer feedback.

It should be noted that not every vendor on this list offers a single consolidated solution that tackles both issues. More often, vendors will have two separate products that can be deployed together, or some vendors only offer products that target one or the other.
