Over the past 2-3 years, cybersecurity leaders and practitioners have faced immense pressure to keep up with the latest tactics, techniques, and procedures (TTPs) adversaries are relying on to gain initial access into your environment and deploy malware.
Complicating matters further, the shift to work-from-home and hybrid workforces have forced many organizations to adopt cloud-based tools for remote business collaboration and to increase productivity.
Although Microsoft Office 365 continues to be the leading cloud-based software provider for business collaboration, many organizations don’t understand the breadth of cybersecurity capabilities they have access to as part of their E5 licensing.
We see that many organizations and even our own customers fail to take advantage of Microsoft’s 365 E5 security capabilities. In this blog, we’ll explore the benefits of Microsoft 365 E5’s security stack and why you should partner with an MDR for Microsoft provider to make the most of out of your Microsoft investment.
While there are countless cybersecurity tools in the market that all promise the same thing – to protect your business against cyber threats – not many deliver on their promises. In fact, it’s likely that your team is often left with too much data, too many alerts that are left uninvestigated, and an increasing number of false positives that you need to wade through. According to the Neustar Cyber Threats and Trends Report, 39% of cybersecurity teams receive alerts from 7+ tools.
In addition, no matter the size or industry of your business, many of your cybersecurity peers are all facing the same three challenges:
This is where Microsoft Office 365 E5 truly shines. Unlike many other cloud-based productivity tools, Microsoft 365 E5 is a cost-effective solution that will easily scale alongside your business. What’s more, the real advantage of the E5 license is that it comes with Microsoft 365 Defender, a suite of built-in security tools that incorporate its security and compliance functionalities right into the operating system so you can consolidate the best-in-class tools in one ecosystem.
Microsoft 365 Defender allows your team to have the same threat prevention, detection, and response capabilities that you would have needed at least four distinct security vendor tools to fulfill. By leveraging Microsoft 365 Defender, your organization can easily experience cost-savings of 50-60% when compared to the cost of engaging a multi-vendor, best-of-breed security tool stack.
So why do so many organizations fail to take advantage of Microsoft’s suite of advanced cybersecurity tools? This is likely due to two reasons:
Microsoft 365 Defender enables your team to initiate response actions to keep malware from spreading, terminate sessions to prevent adversaries from stealing data, and purge malicious files. Your team is also significantly better equipped to deal with the three most used attack vectors used in real-world threat scenarios: phishing, privilege abuse, and malware.
According to our latest threat report, Disrupting Initial Access, email has been widely used as a delivery vector by cybercriminals. In 2020, email accounted for 66% of all incidents we saw in customer environments and though its use decreased in 2021, we saw a resurgence of email-based malcode in 2022. Therefore, phishing, and other types of business email compromise (BEC) attacks, are a significant threat to your organization.
Microsoft Defender for Office 365 allows your team to prevent BEC attacks via robust filtering capabilities, identify suspicious content and attack patterns through its AI-based threat detections, automatically purge malicious emails and files, and conduct email-focused threat investigations and threat hunting.
The 2021 Verizon Data Breach Investigations Report (DBIR) stated that some form of privilege abuse was used in 75% of all breaches investigated in the report. Threat actors often rely on credential theft to obtain admin privileges for lateral movement across your environment to exfiltrate data.
Microsoft Defender for Identity leverages Azure Active Directory so your team can govern and protect user identities:
Most importantly, Microsoft Defender for Identity allows you to get real-time insights all mapped to the techniques listed in the MITRE ATT&CK framework.
In addition to using BEC attacks, threat actors are using a variety of techniques such as drive-by social engineering attacks (e.g., SEO poisoning) to deploy malware and ransomware in their victims’ environment. As noted in the Disrupting Initial Access report, eSentire’s Threat Response Unit (TRU) saw a surge in drive-by cyberattacks, from 7% in 2020 to 34% in 2021. It’s clear that cybercriminals are evolving their tactics as necessary to evade email filtering controls and improvements in Phishing and Security Awareness Training (PSAT).
Microsoft Defender for Endpoint allows your team to isolate ransomware, stop data exfiltration, and block hands-on-keyboard attackers by quarantining files, blocking known bad or suspicious hash values, terminating malicious processes, conducting reboots of affected systems, and eradicating cyber threats.
“The Microsoft Defender stack is comprised of an endpoint security solution, an identity solution, an email solution, and a cloud security solution,” says Kurtis Armour, Vice President of Product Management at eSentire. “Together, those capabilities encompass everything you need to be able to stop a threat. From phishing and social engineering to lateral movement and initial code execution, the vectors that are exploited in nearly 100% of attacks are covered by Microsoft Security.”
Even though the Microsoft 365 Defender arms your team with a suite of high-quality cybersecurity tools, you still need the right expertise to configure the tools properly and manage them 24/7.
The reality is that many cybersecurity teams are still outnumbered against the onslaught of cyber threats and security alerts they face every day. It’s likely your team is experiencing the same pain points:
Herein lies the need for a Managed Detection and Response (MDR) for Microsoft provider. Unlike traditional MSSPs who focus primarily on preventative measures and a birds-eye view of your security posture, an MDR provider will get in the trenches with you.
In other words, MDR providers come equipped to take response and remediation actions on your behalf so you can get peace of mind. This is especially beneficial from a Microsoft standpoint since the Defender suite comes equipped with response and remediation capabilities that a team of 24/7 Cyber SOC Analysts can leverage.
Remember, the key difference between response and remediation are the outcomes:
Rather than trying to adopt a DIY approach to managing your Microsoft security stack, it’s much more cost-effective to partner with an MDR for Microsoft provider so you can get access to a team of Elite Threat Hunters and 24/7 Cyber SOC Analysts that you can trust.
By engaging an external MDR provider, you can achieve 24/7 visibility across your Microsoft ecosystem, ongoing cybersecurity event monitoring, threat detection and investigation, and complete response capabilities – all at a significant cost-savings. When compared to the DIY approach, you can reduce the total cost of ownership for threat detection and response by 50% if you engage eSentire MDR:
