Introducing rogue DHCP discovery in ManageEngine OpUtils. With this new feature, OpUtils lets administrators discover, classify, and continuously monitor DHCP servers across the network directly from the IP Address Manager console.

Top tips is a weekly column where we highlight what's trending in the tech world and list practical ways to explore these trends. This week, we are tackling something almost everyone does without thinking twice: connecting to public Wi-Fi (and what it could be costing you without you ever knowing). You are at an airport, a coffee shop, or a hotel lobby. You notice your data plan is running low and scroll through the available networks. And there it is: Free Wi-Fi—no password required.

Network outages are still painfully expensive, and configuration mistakes are one of the biggest culprits. A 2023 analysis of Uptime Institute data shows that configuration and change management failures are the top cause of major network outages, responsible for around 45% of network incidents. Even a small configuration slip on a core switch can cascade into large-scale downtime. That’s why consistent, well-governed network device management is key to keeping business services uninterrupted.

Every Windows device your organization deployed before 2025 carries a set of certificates in its Unified Extensible Firmware Interface (UEFI) firmware. They've been there since 2011, quietly doing the work of validating boot signatures so nothing untrusted runs before the operating system loads. Most IT teams have never had a reason to think about them. That's about to change.

Network vulnerability management is no longer a periodic security task. As networks expand across locations, vendors, and OSs, vulnerabilities can emerge quietly through configuration changes, outdated firmware, or delayed patching. Without consistent visibility and automation, teams often discover risks only after they affect availability, security, or compliance. Effective vulnerability management requires continuous awareness, structured assessment, and controlled remediation.

Five Worthy Reads is a regular column highlighting five noteworthy articles we've discovered while researching trending and timeless topics. In this article, we're exploring post-quantum cryptography (PQC), which is a rapidly evolving field focused on protecting sensitive data from the future threat posed by quantum computers. Current digital security relies heavily on public key cryptography to protect sensitive information, secure communications, and verify identities.

In the current threat landscape, the pressure on security operations center (SOC) teams has never been higher. Yet for many organizations, the reality of daily security operations is less high-tech threat hunting and more of an uphill battle against manual processes and fragmented data. To understand why SOC teams are burning out, let's walk through a typical morning of an SOC analyst.

At some point, every enterprise faces the same quiet operational nightmare: hundreds of users, thousands of devices, multiple locations, and someone in the IT department manually managing who gets access to what. Active Directory (AD) was Microsoft's answer to that problem when it shipped with Windows 2000, and it remains, over two decades later, the dominant identity and access infrastructure in enterprise networks worldwide.

Many organizations invest heavily in backup solutions but still face a critical gap: the absence of a well-defined backup retention policy. Without a structured retention policy, backups may either be stored longer than necessary, driving up costs, or deleted prematurely, increasing compliance risks and limiting recovery options. In critical scenarios like ransomware attacks or system failures, organizations may find that their backups are incomplete, outdated, or unusable.

Data loss is no longer a rare event—it is an inevitability. From ransomware attacks to accidental deletions, organizations must be prepared not just to prevent incidents, but to recover from them quickly and reliably. Modern threats increasingly target backup environments, making recovery readiness a critical component of any data protection strategy.
