Organizations today face a common challenge: sensitive data is everywhere. It lives across collaboration platforms, endpoints, databases, SaaS applications, and cloud storage systems. Employees and partners need to access and share information quickly, often across teams, organizations, and even countries. At the same time, regulatory requirements, security mandates, and privacy obligations demand stronger protection for sensitive data.

As organizations increasingly rely on Microsoft Teams for internal and external collaboration, the platform’s chat and file-sharing capabilities have become central to daily operations. However, speed and flexibility come with risk. User-managed collaboration tools can create challenges in maintaining control over data access and enforcing compliance with organizational sharing and usage policies.

Microsoft SharePoint has a mature, well-structured security model. It gives organizations control over who can access sites, libraries, and documents, and for most day-to-day needs, it works well. But there is a fundamental limitation built into how SharePoint security works: it controls access based on role, not on the sensitivity of the content itself.

In 2025, universities in the United States and Australia found themselves squarely in the crosshairs of persistent and evolving cyber threats. Higher education institutions manage highly sensitive personal information, financial details, healthcare records, and research data, making them prime targets for sophisticated attackers, ransomware gangs, and even hacktivists. As cybercrime escalates globally, the education sector is facing some of its most disruptive and consequential breaches in years.

As Winter Storm Fern made its way across the US this weekend, children across the country were glued to phones, computers, or televisions as they tried to guess how long they would be out of school this week. Little do they know, however, the data, science, and lack thereof, that goes into that decision. School closures are the very public end of a complex and fast-changing dataset that is highly dependent on locality and can be wildly different on either side of a district line.

The regulatory and compliance landscape evolved rapidly in 2025, with changes key changes affecting cybersecurity, privacy, and protective security. This review breaks down key compliance changes, offering insights into new requirements and how to ensure compliance in 2026.

Data security in 2025 was less about reacting to breaches and more about surviving in a world where data is everywhere, attackers are faster, and trust is fragile. While the core goal of protecting sensitive information hasn’t changed, how organizations approach security has evolved significantly.

In today’s high-turnover work environment, we’re watching something unusual happen: record numbers of security cleared, experienced professionals are re-entering the job market. They’re leaving shuttered programs, reorganised agencies, downsized contractors, and sometimes entire departments caught in a budget reshuffle. Conventional wisdom says these people are an asset anywhere they land.

Data governance and protection are crucial in safeguarding sensitive information. Proper classification and data labeling are essential to ensure that the right people access the right information. Failure to implement these practices can result in data breaches, financial losses, and reputational harm. To help with this, Microsoft offers sensitivity labels that classify and protect data as part of the compliance and security capabilities of Microsoft Purview Information Protection in Microsoft 365.

Starting November 10, Phase 1 of the US Department of Defense’s CMMC 2.0 program went into effect, marking the start of a phased three-year rollout. Phase 1 begins with Level 1 and 2 self-assessments and culminates with the full implementation of program requirements in Phase 4. Organizations that fail to demonstrate compliance will not be eligible to bid on U.S. Defense contracts.
