Many organisations think their current email security systems are up to the job of protecting them. Unfortunately traditional email security strategies can fall short of keeping organisations safe.
So what can you do? Here are Bridgeway's top tips:
3. Deploy a cloud-based email security solution. More and more organisations are choosing a cloud-based solution because of cost, lack of security staff and skills, ease of deployment and management. As well as improved security efficacy.
4. Ensure your email security solution has a scanning layer that not only blocks spam and viruses, but also protects users from phishing, ransomware and impersonation fraud. Technology capabilities such as URL filtering, attachment sandboxing, instant preview and safe-file conversion of all incoming attachments are must-haves.
5.Your archive should be immediate – with data captured in transit – as well as tamper-proof and perpetual. Your users need the ability to sync files, folders, data and calendars and recover them if an attack occurs.
6. Bolster your business continuity planning by implementing a separate, always-on solution that provides multiple access systems through the web and mobile apps.
7. Educate staff. Regular end-user training can help maximise your organisation’s ability to respond to cyber threats, ensuring staff remain vigilant against email-borne threats.
8. Educate the board. CISOs must ensure cyber resilience is identified as a priority by the board. Once the board can understand the value and ROI that comes from having a robust cyber resilience plan, they will trust and buy-in.
9. In order to keep the business running as normal, the organisation will also need access to emails even in case of a minor or even catastrophic failure of the organisation’s email service. Whether the email service is hosted on-premises or in the cloud, any service outage needs to be mitigated.
10. It's not just email. As threats are getting more and more sophisticated, malicious links can be delivered to users in many ways, including via embedded links in otherwise harmless websites, through instant messaging systems, via social network sites, and by ad networks. Remember this and consider introducing a web security service.
