Lintasarta Strengthens Its SOC and Delivers AI-Powered Security with Exabeam

Lintasarta stands as one of the largest Information and Communication Technology (ICT) providers for enterprises in Indonesia, serving over 2,300 customers with an integrated suite of connectivity, cloud, and cybersecurity services. Understanding that trust is foundational to their success and their customers’ success, Lintasarta sought a security operations platform that could deliver the AI-powered security needed to safeguard their digital landscape.

“In this digital and AI era, cybersecurity is not optional. Rather, it is foundational,” states Gunawan Prasetyo, Head of Cybersecurity Delivery and Operation at Lintasarta. “We believe that cybersecurity is much more than a defense. It plays a vital role in assuring confidence in the digital economy at Lintasarta.

The Challenge: Alert Fatigue, Obscured Visibility, and Manual Process

Lintasarta’s internal security operations center (SOC) encountered significant operational challenges with its existing security tools, especially as their managed security service provider (MSSP) business grew. The analysts responsible for protecting Lintasarta’s own corporate network and the networks of their customers were experiencing severe alert fatigue from a large volume of low-fidelity alerts, which obscured real threats to the business.

The team struggled with a lack of innovative threat detection capabilities, particularly in terms of behavioral analytics and insider risk. This gap resulted in manual, time-consuming investigation processes, leading to longer mean time to detect (MTTD) and mean time to respond (MTTR) metrics. Furthermore, the previous solution had scalability limitations, making it difficult to efficiently onboard new MSSP customers with varied environments and lacked a single, correlated view across multiple security tools.

“As our MSSP business grew, we realized the need for a SIEM platform that was more intelligent, automated, and behavior-driven,” explains Prasetyo.

The Solution: An AI-Enabled, Behavior-Driven Platform

Lintasarta began a search for a new platform, evaluating several leading SIEM and extended detection and response (XDR) solutions against a strict set of criteria, including advanced user and entity behavior analytics (UEBA) capabilities, automation, multi-tenant scalability, and ease of integration. The company ultimately chose Exabeam to be the core of its security platform.

“Exabeam’s robust behavioral analytics engine, intuitive investigation workflows, and automation capabilities that fit our AI-enabled SOC vision led us to ultimately choose Exabeam,” says Prasetyo.

The collaboration between the Lintasarta and Exabeam teams ensured the onboarding process was structured and smooth. The intuitive nature of the Exabeam platform allowed Lintasarta’s SOC analysts to adapt quickly, develop new use cases, and deliver immediate value internally and to customers through enhanced threat detection and investigation.

The Results: Driving Efficiency, Resilience, and Customer Value

Since implementing Exabeam in 2020, Lintasarta has transformed its security operations, moving from traditional rule-based monitoring to modern, behavior-based threat detection.

Lintasarta has now gained powerful new capabilities to protect internal and customer assets with the help of Exabeam UEBA. By baselining normal user and device behavior, for example, Exabeam automatically identifies anomalies and risky activities that are often indicators of insider threats or lateral movement. This has allowed the Lintasarta SOC to begin detecting stealthy attacks that were previously invisible to their internal defenses.

Other key results include:

• Accelerated Threat Response: By automating alert correlation and streamlining investigation timelines, Lintasarta significantly reduced MTTD and MTTR, leading to better SLA performance for its customers and yielding higher value in their own SOC.
• Improved SOC Efficiency: The Exabeam New-Scale Security Operations Platform enabled the Lintasarta team to handle a growing customer base and increasing data volumes without a linear increase in headcount. Analysts are now free from manual triage and can focus on high-value work like proactive threat hunting.
• Scalable and Sustainable Growth: The platform’s multi-tenant architecture has enabled faster, more efficient onboarding for new MSSP customers, providing a foundation for sustainable business growth and higher customer retention.
• Stronger Cyber Resilience: The enhanced visibility and early detection of suspicious activities have reduced the dwell time of potential attacks, strengthening the cyber resilience of both Lintasarta and its clients.

“Exabeam is the key partner of enabling us to scale in a sustainable way with our cybersecurity business,” Prasetyo notes.

“Exabeam’s robust behavioral analytics engine, intuitive investigation workflows, and automation capabilities that fit our AI-enabled SOC vision led us to ultimately choose Exabeam,”
