SIEM tools like ManageEngine Log360 correlate events from endpoints, servers, and identity systems to detect signs of lateral movement—such as multiple logon attempts, access to multiple machines, or the use of administrative tools like PsExec. Log360 maps these behaviors against frameworks like MITRE ATT&CK to expose advanced threat paths early.

Did you know that, in the first quarter of 2025, organizations faced an average of 1,925 weekly cyberattacks with a 47% increase compared to the same period in 2024? This underscores the urgent need for enhanced security strategies that provide real-time visibility, rapid threat response, and proactive defense across IT environments.
Key security challenges in IT landscape
The following are the key challenges in the current IT landscape, especially from a security, operations, and transformation standpoint:
- Increasing cybersecurity threats: Sophisticated ransomware, phishing, and insider threats are on the rise as attackers exploit hybrid work models and attack surfaces expand. Managing security across endpoints, cloud workloads, and legacy systems simultaneously has become increasingly complex.
- Managing hybrid and multi-cloud environment: With organizations operating across on-premises and cloud environments, inconsistent security policies and limited visibility pose major challenges. Integrating monitoring tools across diverse platforms adds to the complexity.
- Alert fatigue and limited threat context: IT and security operations center (SOC) teams are overwhelmed by high alert volumes, struggling to distinguish real threats from noise. The absence of correlation and context further delays effective incident response.
- Skill shortage and talent gaps: A shortage of skilled cybersecurity professionals leaves existing teams under-resourced and overburdened. Continuous upskilling is essential to keep pace with evolving threats and technologies.

|
| Sensitive file access by unauthorized user | A junior employee accesses sensitive HR or finance folders outside their role. |
|
| Privileged account misuse | An admin user accesses multiple high-privilege resources unusually after work hours. |
|
| Insider threat (bulk file deletion or downloads) | An employee downloads or deletes large volumes of files before resigning. |
|
| Access to cloud applications from suspicious IP | A user logs into Microsoft 365 from an IP address in a high-risk country. |
|
| Firewall or VPN anomalies | Firewall rules are changed without a change ticket or a VPN tunnel drops repeatedly. |
|
| Third-party application misuse | A rarely used third-party tool suddenly makes multiple system-level changes. |

SIEM's role in meeting the regulatory requirements of IT sector
A SIEM solution plays a critical role in helping IT environments maintain compliance with various regulatory frameworks such as ISO 27001, SOX, the GDPR, and the PCI DSS. By continuously collecting, monitoring, and storing logs from across the infrastructure, a SIEM solution ensures complete visibility into user actions, system changes, and security events—a key requirement for most audits. It provides prebuilt and customizable compliance reports, making it easier to demonstrate adherence during regulatory reviews. Additionally, SIEM helps maintain immutable audit trails, ensuring that all access and changes to sensitive systems are recorded and retained securely.
Beyond logging, SIEM platforms like ManageEngine Log360 support real-time alerting and response to non-compliant behavior, such as unauthorized access, privilege misuse, or data leakage. This enables IT teams to take proactive steps to prevent violations before they escalate into reportable incidents. SIEM tools also enforce RBAC and log retention policies that align with specific compliance standards. Overall, SIEM bridges the gap between security operations and compliance mandates by offering a centralized, accountable, and auditable security monitoring system that satisfies both internal and external regulatory expectations.
