Email security: Never more important

Email security remains as important as ever, with the majority of cyber-attacks, including ransomware attacks, still being launched through email using a combination of social engineering, phishing, malicious links and weaponised email attachments.

Email remains the easiest and most effective channel of attack with the number of emails being sent on a daily basis expected to surpass 293 billion by the end of 2019. Despite this, email is the weakest link in most organisations’ security strategies, with many failing to address vulnerabilities in popular email platforms such as Office 365.

With the reliance on email and associated threats likely to continue to grow, businesses need to address this threat with a combination of security awareness training and automated tools to reduce the likelihood of infection and speed up the detection of and response to email borne threats. Underlining the importance of email security, it is a core component of the UK National Cyber Security Centre’s Active Cyber Defence (ACD) initiative.

  • The myth of email as proof of communication

    Organisations are facing an increasing need to be able to show exactly what was communicated, to who and when. The ubiquity of email provides an ideal means of doing this, but it needs additional capabilities; to ensure that the email is stored in an immutable form and is time-stamped, in a manner whereby the document can be seen as being legally admissible as evidence.

     Whether the need is for ensuring that contract terms are acknowledged and enforced, keeping records of online sales, protecting key information, or whatever compliance requirements or regulation a company must meet, being able to reference an immutable copy of communications between parties has immense business value.

     Essentially, if anyone in an organisation has ever said, “What did we communicate at the time?” then a means of evidential proof is required.
