Protecting Office365: Are built-in security features enough to protect your data?

Protecting Office365: Are built-in security features enough to protect your data?

As our email accounts are the backbone of business communications, it is of no surprise that they have become a magnet for cyber criminals. But do you have advanced email security controls protecting this ‘treasure trove’ of corporate information? Unfortunately, many businesses are still depending on bare minimum-security features offered by email providers such as Office365 to protect their critical data.  However, as email continues to be the number one cyber-attack vector across the globe, businesses need to be strengthening their email security measures to prevent the risk of being compromised.

The email security landscape

If your email security controls are not effectively safeguarding your assets, you may have already fallen victim to a costly phishing attack. Shockingly, the 2019 Verizon data breach report found that one third of data breaches involved phishing activity.

A malicious email which bypasses security controls could devastate any organisation. With the growing prevalence of highly targeted phishing attacks, the risk of an unsuspecting employee getting duped into clicking is higher than ever before. We are no longer talking about scams like the notorious email from the ‘Nigerian prince’. Hackers are now sending highly believable phishing emails posing as your bank, internal teams, suppliers, retailers and local councils, even as security experts it can be tricky to spot a scam!

Phishing attacks which aim to steal login credentials are on the rise. However, this is even more problematic if your employees are recycling passwords. Once a hacker successfully harvests your credentials and accesses your corporate email accounts, they will often attempt to gain access to other critical systems. This greatly increases the likelihood of affecting multiple systems and data, resulting in a largescale breach. To prevent this unfortunate human habit, businesses should encourage all employees to use password managers such as LastPass. This allows employees to randomly generate secure passwords which are very difficult to guess using brute force attempts.

How can businesses address these challenges?

Basic Office365 anti-spam filters are simply not enough to keep your business safe from these relentless attacks. To keep hackers at bay and prevent the risk of pervasive attacks, you must have multiple layers of email security controls. However, many organisations face the challenge of choosing an email security strategy which is cost effective, user friendly and blocks advanced security threats.

As there are multiple points of entry which a hacker could exploit, protecting your Office365 accounts can seem complex. However, using the right tools you can eliminate your security weaknesses by deploying effective security policies and closely monitoring user activity.  To reduce the risk of Office365 being compromised it is important to monitor the devices and users who are accessing accounts. This increases visibility so that you can identify and prevent potential cyber breaches in real-time.
