What is email security?

Email is cybercriminals’ method of choice for entering business networks and stealing from them; email is also most organizations’ primary means of communications. Thus, email security safeguards employee communication and reduces risk with targeted threat protection, data leak prevention, and enforced email security controls. Multiple layers of email security protection are required to stop known and emerging email-borne threats before they reach your organization’s environment.

Why is email security important?

Organizations are seeing a massive rise in cyberattacks. Legitimate business emails can contain the sensitive information cybercriminals need in order to access and exploit critical business systems. Phishing emails can give cybercriminals instant access to an organization’s entire network in just one click. Even with proper email security training, data breaches can still occur. Organizations need cloud-based email solutions that offer encryption, targeted threat protection, data leak prevention, and enforced email security controls.

What should organizations look for when evaluating email security companies?

Organizations need an email security solution that stops malware, spam, and advanced threats using targeted threat protection, data leak prevention, and enforced email security controls. While team members should always be trained in proper email security, solutions need to be automated, cloud-based, and offer encryption. Email security solutions should work in the background and not impede user productivity. When evaluating email security companies, organizations need to find an email security partner with the right tools to prevent, detect, and respond quickly to phishing attacks and other email-based threats.
