Cybercriminals are not standing still. The decline of headline-grabbing ransomware gangs may offer some false comfort, but beneath the surface, more agile and sophisticated attackers are exploiting emerging vulnerabilities and tools.
Among their most persistent targets is Microsoft Active Directory (AD). It is the foundation of access and identity in more than 90% of organisations globally. As AD environments grow more complex through hybrid deployments and automation gaps, the attack surface only widens.
Securing AD is not just a matter of setting policies and hoping for the best. If that’s still an approach your business follows, you might be in trouble. The risks are escalating. From ransomware-as-a-service (RaaS) and AI being used in attacks, the margin for error is vanishing.
The good news? There is a clear and achievable path to strengthen your organisation’s security posture.
Drawing on insights from a survey of AD users, this article sets out four key priorities: resilience, automation, unified management, and security. Together, these elements form the backbone of modern AD protection.
Resilience: Disaster readiness in minutes, not weeks
Downtime is one of the most expensive conditions an organisation can suffer. Whether triggered by a ransomware attack, misconfiguration or system error, the impact of losing access to AD can be swift and severe. It can halt operations, prevent authentication, stop communications, and block access to essential systems. Yet, as the survey findings reveal, only 15% of organisations have an isolated, clean standby replica ready to go.
Because they have backups, organisations often overestimate and under-test their ability to recover. Traditional backup tools, still used by 32% of businesses, can’t keep up with the specialised demands of hybrid AD environments. They’re slow, fragmented, and often fail when needed most.
By contrast, a modern resilience strategy hinges on instant forest recovery. Solutions supporting these strategies must enable full restoration of AD in minutes rather than days. Crucially, they must support both on-premises and cloud environments.
This hybrid recovery capability has become essential, as AD is no longer contained within a single domain or physical network. It’s the difference between a brief interruption and a full-scale crisis.
Automation: Reclaiming IT person-hours and reducing risk
Manual work is the silent killer of IT productivity. It slows response times, introduces human error, and ties up skilled staff on routine tasks. Yet 47% of organisations still rely on native, highly manual tools. A further 14% are still writing custom scripts to handle daily operations. Why? In an era of AI-assisted cyberattacks and shrinking IT teams, that’s a dangerous combination.
Automation is the solution. It eliminates repetitive processes like provisioning, deprovisioning, and group management, resource-heavy tasks prone to error. It also enables real-time monitoring and anomaly detection, ensuring that threats are identified and mitigated before they escalate.
Effective automation doesn’t mean losing control. It is about gaining time and visibility while reducing costs and risks. With the right tools, IT teams can shift focus from firefighting to forward planning and strategic initiatives. These support innovation rather than simply maintaining systems.
Unified management: Reducing risk through visibility
Fragmented management tools are a gift to attackers. Each disconnected interface represents a potential blind spot, and every integration gap is a point of weakness. With hybrid AD now the norm, mixing on-premises AD and Entra ID, organisations must consolidate.
Almost half (49%) of respondents said they already use a single-console solution to manage their hybrid environments. Importantly, 88% see such visibility as crucial. That’s because unification simplifies oversight, compliance, incident response, and role-based access control.
A single-pane-of-glass approach enables IT leaders to enforce policy across all environments, audit user behaviour, and respond faster to incidents. The findings also highlight how unified management reduces training needs and ensures consistency. This is an especially valuable advantage for organisations facing high staff turnover or skills shortages, which affect 31% of large enterprises.
Security: From reactive to proactive with zero trust
Despite being the backbone of enterprise identity, AD security is often treated as an afterthought. Therefore, it is unsurprising that only 17% of organisations effectively monitor changes to sensitive AD components. Of even more concern, nearly half (48%) lack proper privilege assignment processes. It leaves the door open for insider threats and accidental exposure.
The answer lies in shifting from a patchwork approach to one rooted in zero trust. That means enforcing least-privilege access, conditional policies, and mandatory authentication protocols across the board. It also requires real-time auditing that flags unauthorised changes as they happen and not hours or days later.
Security in 2025 must be predictive, not passive. Hybrid AD environments require continuous verification, not just perimeter defences. And with attackers now using AI to pinpoint weaknesses faster than ever, a proactive security posture is mandatory.
Closing the gaps before they widen
Based on this data, this isn’t a minor concern. It’s a blaring alarm for any organisation that relies on outdated tools to secure AD. It reveals a landscape where many organisations still depend on legacy tools, manual fixes, and siloed solutions to manage their most critical identity infrastructure. But it also shows the way forward.
By prioritising resilience, embracing automation, consolidating management, and enforcing security, IT teams can shift from being exposed to being in control. To me and many end users I engage with daily, these are not just best practices but imperatives for an enterprise that depends on Active Directory, which, in 2025, is practically all of them.
With the right strategy and tools, it’s possible to protect your hybrid AD without adding more burden to your team. The time to act is not after the next breach or failure. It’s now.
