The most targeted platform in the world demands the best email security.
Email is the most universal communication tool for businesses and more than 300 million users depend on Microsoft 365 for email, so it’s unsurprising that 94% of all attacks start with email.
Hackers have evolved their methods of attack- they’re attacking at the perimeter and targeting people inside the organisation, using social engineering to dupe employees, amplifying the attack’s impact by spreading internally, and stealing domains and brands to attack customers, employees, and broader supply chains.
For organisations who rely on Microsoft 365, you should consider the below factors:
However, preventing or limiting the consequences of an attack calls for more than enhanced email security. Preventive measures need to be part of a larger strategy of cyber resilience that embraces backup and recovery, business continuity and compliance, as well as the ability to identify and block threats that originate on the web.
What about Microsoft 365 security?
Microsoft 365 for email does come with an extensive set of protective mechanisms, however many organisations will require a greater degree of control, resilience, and more extensive protections than Microsoft’s productivity suite can provide.
For instance, the Advanced Threat Protection (ATP) security service offering for E5-level subscribers provides a degree of protection against malicious URLs, phishing messages and attachments. But it doesn’t actively scan all email content for such threats, and its Safe Attachments feature relies entirely on sandboxing to detect malware. Other, more sophisticated techniques, such as deep content inspection, static analysis, and multi-stage threat analysis, are not used, potentially leaving your organisation at risk.
Defence in depth
We would recommend operating ‘defence in depth’, a layered approach to cybersecurity. When used in conjunction with the native security features of Microsoft 365 this will provide a much greater degree of cyber resilience.
With this strategy, if one security control proves ineffective others are already in place to fill the breach. Some of the key elements of a defence in depth strategy include:
By deploying solutions from third parties to shore up the native security of Microsoft 365, you will benefit from much more advanced features, alongside avoiding a security monoculture and making it harder for cybercriminals to penetrate defences.
