Most companies take it for granted that their data is going to be secure by default when they roll out Microsoft 365. Far from it, actually.
Office 365 does have built-in security when it comes to spam blocking and basic MFA (multi-factor authentication), but that is not enough security. Without having the right and multi-layered security setup, your business is still at risk of being hit by phishing, credential compromise, ransomware, and other attacks.
As Adam Bowles, ACT360 Director of Web Services, suggests to clients: "Office 365 is a starting point, but not a full security solution. True protection is about layering the appropriate tools, such as endpoint detection, monitoring, and proactive response, on top of a strong Microsoft 365 deployment."
The False Sense of Security
Small and medium-sized enterprises prefer Microsoft 365 because it is reliable, affordable, and familiar. However, it is not a good idea to rely solely on its out-of-the-box security features. Remember the following facts:
- 74% of breaches involve the human element, like phishing and stolen credentials, based on Verizon's 2023 Data Breach Investigations Report.
- Misconfigured Office 365 settings, like open file-sharing links, default admin rights, or lack of advanced threat detection, are frequently targeted by attackers.
This means that while Microsoft 365 provides a foundation, you still need additional protection.
What Office 365 Protects — And What It Doesn’t
Office 365 includes:
- Basic spam and malware filters
- Optional MFA
- Data loss prevention (DLP) tools
- Basic admin activity logging
But not:
- Advanced endpoint detection and response (EDR)
- Real-time breach alerts and threat hunting
- Deep configuration and patch monitoring
- Ransomware rollback or containment options
What ACT360 Adds: Real Protection That Fills the Gaps
At ACT360, we augment Microsoft 365 security by overlaying it with enterprise-grade tools like Huntress EDR and custom security rules crafted based on specific business needs.
This is what we do to secure our customers:
- Endpoint Detection & Response (EDR): Huntress scans continuously for suspicious activity, complemented by a 24/7 ThreatOps team to respond if needed.
- Proactive Monitoring: We track admin access, MFA, and login activity to identify anomalies early.
- Breach Containment: When the threat is detected, we lock down the affected account or device prior to spreading.
- User Training & Hardening: We educate your staff members to detect phishing scams and employ best practices on all accounts.
Don't Wait Until It’s Too Late
Cybercriminals don't care about how large your business is, but how exposed. One compromised email account can unleash thousands of records, client data, or internal systems.
Acquiring layered protection today will pay for your business in reduced downtime, legal fees, and reputation loss later.
