Email security, or filtering, does more than just flag spam emails. It protects your accounts from harmful viruses and phishing attacks, as well as internal email threats. In 2020, Mimecast reported a 64% increase in email threats.
What is Email Security?
Email security protects your accounts and its content against unauthorised access or loss or compromise of data through theft.
Incoming emails will be inspected for suspicious links and files. These can be from external and internal contacts. Additionally, the sender’s email address will be checked to see if it is a spoof. This helps against impersonation attacks, where an email attempts to impersonate someone in the company to gain sensitive data.
Email security software also learns from you. We’ve all had a ‘check your spam’ request. As you give permission to certain domains or types of emails, your security will learn what is safe.
Why is it important to have email security?
Email is the top way cyber criminals will try to infiltrate your organisation. In fact, more than 90% of cyber-attacks start with email. Having email security measures in place will:
- Help protect your organisation from ransomware, spam, malware and phishing attacks – therefore preventing theft or loss of data
- Protect your brand and reputation
- Saves downtime spent dealing with an incident
Having email security in place also helps reduce human error. Some employees may not be aware that they have received a phishing email, or what to look out for. Email security stops that email from reaching them in the first place, removing the threat. In addition, it can also protect against malicious, internal attacks.
As well as email security, you need to consider what will happen if something goes wrong. Do you have policies and protocols in place should an incident occur? It is always best to plan for the worst.
Having a backup is also crucial. Not just for your email though. An attack may reach you via email, but that doesn’t stop it from spreading to all files. Ensure you have a sufficient backup so that you won’t lose work or be held to ransom if you do fall for an attack.
