Key Challenges
Due to low visibility into its systems, Unitel struggled to quickly resolve incidents and protect its sensitive data.
Key Results
After automating complicated manual processes and gaining comprehensive visibility, Unitel now responds to incidents in real time, which has lowered the risk of security breaches.
Unitel, Mongolia's leading information communications technology group, provides hundreds of thousands of subscribers with mobile telephone services. Keeping its network resilient requires securing all digital assets and network resources, as well as maintaining the confidentiality, integrity and availability of information. But Unitel’s previous SIEM lacked the data analysis, monitoring and threat intelligence capabilities for effective incident investigation and response, which made cyber threats a serious risk for the business.
Unitel needed a new SIEM solution that could provide full-stack, real-time visibility into its cybersecurity posture and enable quick recovery when the inevitable incident did arise. After evaluating 10 solution providers and conducting multiple technical assessments, Unitel chose Splunk. “Splunk offers the flexibility, customizability, scalability, ease of use and integration capability we need for executing our security operations,” says Mendsaikhan Amarjargal, CISO of Unitel group. “We were also impressed with Splunk as a thought leader in the security space.”
Security requirements are multifaceted at Unitel. “We have to maintain good security controls to prevent cyber threats and vulnerabilities while monitoring and responding to security incidents. We also have to enforce and improve policies and procedures to systematically manage our sensitive data,” Amarjargal explains.
Beyond these requirements, Unitel needed an all-in-one data analytics platform. Log management became much simpler on the centralized Splunk platform, cutting the time needed for log search and ingestion by half across all its data sources — from network traffic and intrusion detection logs to endpoint protection and threat intelligence information.
“Splunk gives us the big picture and full visibility into the cybersecurity posture of our organization. This means we can identify and respond to security threats in real time, reducing the risk of security breaches and the impact of security incidents,” says Amarjargal. “We also appreciate how Splunk’s partner Unity helped us deploy the solution with ease while providing initial training for our engineers and coordinating with Splunk to ensure we receive optimal support.”
In the past, it used to take an hour for us to manually find and fix a single problem, which is already too long in today’s fast-paced world. The Splunk platform automatically correlates and analyzes data, which has made incident response two to three times faster than before.
Thanks to Splunk, Unitel resolves issues much faster, keeping systems up and running around the clock. “In the past, it used to take an hour for us to manually find and fix a single problem, which is already too long in today’s fast-paced world,” says Amarjargal. “The Splunk platform automatically correlates and analyzes data, which has made incident response two to three times faster than before.”
Faster incident response has ripple effects throughout the business. Customers are happier because they’re minimally affected by issues, and faster fixes also extend battery life for user devices. Within Unitel, automating security event correlation has saved hours of manual work and halved the time spent on system integration and data parsing.
“Splunk is a robust and reliable cybersecurity solution that helps us safeguard our network, infrastructure, applications and data. Our systems are better prepared against threats and are better positioned to recover from whatever issues that arise,” says Amarjargal. “As the largest information communications technology (ICT) company in Mongolia, Unitel operates not only in telecommunications, but also other services such as triple play and over-the-top media services. Because Splunk is customizable and flexible, we can easily process data from multiple sources to keep our business digitally resilient.”
In addition to product functionality, Splunk’s large user base in Mongolia is also a bonus for Unitel. “We are able to learn from many other local use cases and derive maximum benefits from Splunk,” Amarjargal explains. Apart from out-of-the-box security use cases, additional applications from the Splunkbase App have been helpful in fulfilling Unitel’s specific needs.
“Right now we’re looking to extend the use of Splunk to other areas such as customer experience management to improve customer service, reduce churn and identify new revenue opportunities,” Amarjargal adds. “We’re also considering using Splunk as an IoT analytics platform to monitor device performance, detect anomalies and improve operational efficiency. Furthermore, we may also put Splunk on network performance monitoring, anomaly detection and troubleshooting.”
