Why Your Business Needs a Microsoft 365 Configuration Review

Microsoft 365 is the backbone for communication, collaboration, and productivity in any workplace. However, with such a powerful tool comes big responsibility and many businesses are unknowingly leaving themselves vulnerable to cyber threats by failing to configure their Microsoft 365 systems correctly and relying on default settings. A Microsoft 365 Configuration Review isn’t just a good idea, it’s essential for ensuring that your business and communications stay secure, compliant, and free from vulnerabilities that could be exploited by criminals. Here’s why:

1.      Identifies Gaps in Security

Microsoft 365 offers top quality security features, but they aren’t always automatically enabled or configured properly. A configuration review will identify the gaps in your current set up, such as weak passwords or authentication methods, lack of encryption, or unauthorised sharing permissions. This will help you proactively fix any recognised vulnerabilities before criminals have the chance to exploit them; thus, keeping your business communications safe.

2.      Strengthens Access Controls

Most businesses will handle a great amount of sensitive data including personal and financial information of customers and employees, and intellectual property. Regulatory compliance such as GDPR standards demand careful data management from businesses and a configuration review will ensure that your policies for data storage, access control, and auditing meet both the legal requirements and industry best practices. This will also reduce the risk of data breaches which can be costly to both your company’s finances and reputation.

3.      Improves User Experience

A configuration review of your Microsoft 365 systems can uncover opportunities to improve your collaboration tools such as Teams and SharePoint to ensure that your employees and clients have access to your correct resources without compromising the security of your systems. Outdated and inefficient settings can often lead to user frustration, downtime, and a lack of productivity.

4.      Reduces the Risk of Phishing Attacks

Phishing scams are the most common and damaging cyber threats that face businesses of all sizes today. A configuration review will ensure that your email security settings include anti-phishing policies, two-step verification (2SV), and other important threat detection tools to strengthen your defences and make it much harder for phishing attempts to land in the inboxes of your employees, protecting both your people and your data.

5.      Adapts to Evolving Threats

Cyber threats are constantly evolving, and criminals are finding new ways to breach your security systems and attack your business. What was considered secure a few years ago, may now be considered a vulnerability in your system so regular configuration reviews will help to ensure your Microsoft 365 systems stay up to date with the emerging risks and take advantage of the latest security updates and best practices.
