Cybersecurity frameworks continue to evolve as organisations face increasingly sophisticated threats. Recent updates to widely adopted baseline security standards are raising the bar—placing stronger emphasis on identity protection, cloud visibility, and endpoint control.

The latest Cyber Essentials changes introduce stricter requirements that go far beyond traditional perimeter security. Multi-Factor Authentication (MFA) is now mandatory across all user access to cloud services, not just privileged accounts. In addition, SaaS platforms, IaaS environments, and previously overlooked shadow IT systems are now fully in scope. Mobile devices are no longer optional—they must be assessed and secured as part of your environment.

For many organisations, this represents a significant shift. Compliance is no longer a checklist exercise—it requires a clear understanding of your entire attack surface, from endpoints to cloud services. Failure to align with these updates can expose critical gaps, increase risk, and impact audit outcomes.

To help break down these changes and their real-world implications, ManageEngine is hosting a live expert-led session designed specifically for IT and security professionals.

With today’s increasingly complex network environments, managing network bandwidth is no longer optional—it is a critical requirement for ensuring stable and efficient operations. Modern networks support a wide range of applications, from real-time communications and cloud services to large-scale data transfers, all competing for limited resources. Without proper visibility and control, network congestion can quickly lead to degraded performance, poor user experience, and potential business disruption.

Effective bandwidth management enables organisations to prioritise critical applications, prevent unnecessary traffic from consuming valuable resources, and maintain consistent network performance across the infrastructure. By implementing the right network monitoring tools and traffic analysis solutions, administrators can gain deep insight into traffic patterns, identify bottlenecks, and make informed decisions to optimise overall performance.

Businesses today rely heavily on advanced network monitoring solutions to maintain operational continuity. These tools play a vital role in proactively identifying issues, strengthening network security, ensuring high availability, supporting scalability, and optimising infrastructure costs. Leveraging flow-based technologies such as NetFlow, administrators can achieve granular visibility into network traffic flows and gain the actionable insights required to effectively manage bandwidth in dynamic IT environments.

Reliable VPN tunnels are essential for maintaining secure communication between branch offices, data centers, cloud environments, and remote users. When a VPN tunnel fails or performance degrades, the impact is often immediate, affecting application access, remote work, and business operations that rely on consistent connectivity across geographically distributed environments.

As networks expand, troubleshooting VPN tunnel issues becomes increasingly complex. Multiple firewalls, WAN links, ISPs, routing domains, and security policies introduce dependencies that are difficult to track without centralized visibility. In many organizations, VPN problems are only identified after users report disruptions, making root-cause analysis more time-consuming and operationally disruptive.

Key Topics

• Why VPN tunnels commonly experience issues
• VPN tunnel parameters that should be monitored

Why VPN Tunnels Commonly Experience Issues

VPN tunnels, particularly IPsec-based site-to-site tunnels, rely on multiple tightly coupled components working in precise alignment. Any inconsistency across encryption settings, authentication methods, routing policies, or WAN conditions can result in tunnel instability, partial connectivity, or complete failure.

Configuration mismatches remain one of the most frequent causes of VPN issues. Encryption algorithms, hashing methods, Diffie-Hellman groups, and security association lifetimes (SA) must match exactly on both tunnel endpoints. These mismatches are often introduced unintentionally during firewall policy updates, platform migrations, or firmware upgrades.

WAN-related conditions such as packet loss, latency, jitter, or ISP link congestion also contribute significantly to VPN instability. These issues tend to appear during peak usage periods and may resolve without intervention, making them difficult to diagnose without continuous monitoring and historical trend analysis.

Routing changes further complicate VPN reliability. Incorrect static routes, dynamic routing advertisements, or policy-based routing rules can redirect traffic away from the tunnel. In such cases, the VPN may appear operational while applications silently fail to communicate.

VPN Tunnel Parameters That Should Be Monitored

The days of relying solely on static monitoring dashboards and manual firefighting are long gone. Today’s environments demand automation-first operations, real-time observability across every layer, and AI-driven intelligence that can make sense of the massive volume of telemetry and logs modern systems generate.

With organizations accelerating their move to cloud-native architectures, virtualization, edge computing, and hybrid infrastructures, IT operations teams now manage ecosystems that are more distributed, interconnected, and unpredictable than ever before. Traditional tools simply can’t keep up with the scale or speed.

This is exactly where AIOps is redefining the game. By combining machine learning, advanced analytics, and automated remediation, AIOps empowers IT teams to detect anomalies earlier, correlate events across domains, and resolve issues proactively—long before users feel the impact. For technical teams, it’s not just an upgrade; it’s a fundamental shift in how operations are executed, optimized, and scaled.

The Evolution of IT Operations - From Reactive Monitoring to Intelligent Automation

In the early days of IT, operations were largely reactive. IT teams would wait for a system to fail—whether it was a server crash, network outage, or application hiccup—and scramble to fix the issue. As technology advanced, the industry shifted towards more proactive approaches. Monitoring tools emerged to detect problems before they escalated, but as IT environments grew in complexity, so did the landscape of tools. Each tool specialized in a different layer: one focused on the network, another on servers, and yet another on applications. This specialization, while useful, led to tool sprawl—multiple disparate solutions with siloed data, leaving IT teams with fragmented insights. Worse, there was no unified system to correlate these insights, resulting in a disjointed view of the infrastructure.

The result? Longer Mean Time to Resolution (MTTR) as teams struggled to connect the dots between alerts and incidents.
