Ensuring SIEM Data Sovereignty: The Case for On-Prem OpenText ArcSight SIEM

Given the critical nature of cybersecurity in industries such as defense, healthcare, finance, and government, ensuring SIEM data sovereignty has never been more important. These organizations must balance the advantages of cloud-based SIEMs with the necessity for strict internal security controls. Existing on-premises SIEM solutions, as their end-of-life approaches, create urgency and threaten the continuity of highly customized, heavily invested cybersecurity infrastructures.

Balancing Risk and Control

While SaaS solutions offer advantages such as lower management costs, increased update frequency, and OpEx flexibility, they also carry significant risks. SaaS-based SIEMs increase the risk of data breaches and exfiltration through reliance on shared cloud infrastructure and third-party security applications. Their dependence on internet connectivity makes them vulnerable to DDoS attacks. Additionally, when data is stored outside of local regulatory judicial regions, compliance and data residency requirements such as GDPR, CCPA, HIPAA, and FedRAMP may not be met.

For organizations prioritizing security, data sovereignty, and compliance—especially those dealing with confidential information, medical records, or PCI data—on-premises SIEM solutions offer a more secure and attractive option.

But Are On-Premises SIEMs Just a Relic of the Past?

Data suggests otherwise. According to IDC's December 2023 Security Analytics TAM report, the total addressable market for on-premises SIEM/Safety Analytics in EMEA is expected to grow from $20.008 billion in 2022 to $21.11 billion by 2027. Additionally, Grand View Research highlights that the on-premises SIEM segment is expected to grow at a compound annual growth rate (CAGR) of 12.8% from 2023 to 2030. This growth is attributed to on-premises SIEMs' ability to provide full control over data, especially for critical management functions such as forensic historical data and disaster recovery.

Why Choose ArcSight for Your On-Premises SIEM?

For organizations prioritizing security, governance, and data sovereignty, ArcSight is a smart on-premises choice. Here are the key reasons:

• Proven maturity: ArcSight will celebrate its 25th anniversary in 2025. Founded on May 3, 2000, the company launched its first product in 2002 and was recognized by Gartner as a visionary in its 2003 "IT Security Management Magic Quadrant" report.
• Leading real-time correlation engine: ArcSight's real-time correlation engine is highly customizable across multiple fields, functions, and categories, enabling organizations to detect threats as they emerge rather than relying on scheduled searches.
• Comprehensive connector support: ArcSight provides over 400 pre-built connectors for seamless integration across various security domains, including anti-virus, databases, cloud environments, mail servers, operating systems, firewalls, IDS/IPS, identity security, network management, and threat intelligence. For unique monitoring needs, custom "flexible connectors" can be developed.
• Free SOAR integration as an extension: To balance on-premises SIEM maintenance costs, ArcSight includes SOAR features as a free extension, enhancing ROI. It also offers seamless, customizable integration with any third-party SOAR platform.
• Comprehensive MITRE ATT&CK coverage: According to a GigaOM evaluation, ArcSight covers all 10 of the most common MITRE ATT&CK techniques.
• Secure threat intelligence and vulnerability data import: ArcSight on-premises allows secure import of threat intelligence and vulnerability data from third-party vendors without exposing it to the cloud.
• Seamless migration: ArcSight enables minimal downtime and continuity by allowing easy transfer of correlation rules and policies during migration from a similar correlation technology-based SIEM.
• Fast and scalable daily management platform: ArcSight Recon simplifies daily management and compliance with powerful analytics, an intuitive user interface, a query language, and actionable insights.
• Guaranteed event processing under attack: ArcSight ensures no event loss during short-term surges in EPS during DDoS attacks by accommodating bursts beyond the licensed limit without penalties.

In Conclusion

Despite the shift to SaaS, on-premises SIEMs still play a significant role, especially in highly regulated or sensitive sectors. ArcSight on-premises offers a mature, reliable, scalable, and highly customizable solution for organizations prioritizing security, data sovereignty, autonomy, and compliance.
