As infrastructures become more complex, the threat vista grows. It is becoming more difficult for IT teams to quickly cut through the noise and detect and respond to security events. At the same time, enterprises are missing valuable insights to protect their IT estate by not having a unified view of their threat landscape.

This is where Security Information and Event Management (SIEM) solutions like Splunk Enterprise Security and data management platforms like Splunk Cloud are hugely beneficial, providing a streamlined view of your data and fast, accurate insights.

While monitoring involves continuous observation collecting and analysing data to help IT teams detect issues, for example. Observability goes several steps further. Encompassing monitoring, it provides visibility into an entire architecture.

Observability is built on three types of telemetry data: metrics, logs, and traces. With this knowledge, IT teams can investigate the root causes of complex system issues, for example. Observability isn’t restricted to one improvement area. However, It can also solve application performance faster, enhance user experience, automate processes, and support cybersecurity and DevOps teams.

Splunk’s mantra is to help organizations build a safer and more resilient digital world. This is precisely why multinationals trust to help improve their digital resilience by adopting security and observability features. Research shows that digital resilience pays off. For example, average savings on downtime costs for organizations with resilience capabilities hit a significant $48 million compared to their peers.

I have recently qualified as a Splunk consultant specializing in Splunk Enterprise Security and Splunk Cloud platform. I have seen the enormous benefits they bring to organizations in unlocking answers hidden in their data to understand better and protect their businesses.

Splunk’s unified platform supports IT and engineering teams and security operations (SecOps) to collaborate at scale to keep digital systems secure and reliable and keep organizations up and running.

All round visibility and rapid detection

Security teams face an increasingly challenging dynamic threat landscape, more sophisticated attacks, and evolving business demands. They need data-driven capabilities, contextual insights, and an accurate, rapid threat detection approach to meet this head-on.

Machine learning (ML) and artificial intelligence (AI) can do much to help here. ML can analyse big data from various sources, such as network traffic, to detect unusual behaviour patterns that might red flag a potential attack. ML and AI can continuously monitor these behaviours and quickly adapt to and learn from new threats.

This is where the intelligence of Splunk Enterprise Security makes its mark, providing data-driven insights for complete breadth visibility, monitoring, detecting, and investigating threats with speed and accuracy.

The Splunk solution is designed to significantly improve your security posture using analytics-driven security and machine learning. Telstra knows that no two enterprises are alike. To that end, the security information and event management (SIEM) solution can be tailored to an individual enterprise’s requirements.

It runs in the public, private cloud, on-premises, and hybrid environments. It combines security data sources from all your services and products, provides a single view of your security footprint across the organisation, and highlights anomalies that may go undetected by standalone monitoring tools. This is provided using predefined dashboards and custom glass table views, including security and performance metrics and trending indicators. A use case library offers a quick route for detecting new and known threats.

Built on an open and scalable platform, the solution breaks down silos and allows enterprises to gain intelligence to protect the enterprise. Organizations can assess risk-based alerting, converting vast volumes of noisy alerts into single incidents. By grouping connected events into a single incident, IT teams can investigate situations faster, come up with a conclusion, and mitigate risks at scale.

Take the growing problem of ransomware, for example, where the Ponemon Institute estimates the average ransom payment is $1 million, with 53% of companies paying up to avoid operational downtime. Splunk Enterprise Security addresses this through ransomware updates via the Splunk ES Content Update, which gives security analysts information on time-sensitive threats and attack methods to help them fight malevolent actors.

Keeping clouds secure

The cloud is where it is all happening, according to Splunk’s The State of Security report, with 50% of respondents saying that most of their SOC team’s time is spent addressing issues in the public cloud. In comparison, just 13% spend most of their time on on-premises issues.

This is where harvesting intelligence from data is invaluable. Spunk Cloud enables users to search, analyse, and visualize their data for actionable insights using the latest streaming and machine learning capabilities to improve security and business outcomes. This includes data at the edge and beyond to detect real-time anomalies and prevent issues across the organization.

Spunk Cloud is continuously updated to ensure data is ready for search requests. Data retention can be customized to meet an organization’s compliance and auditing requirements. Additionally, the deployment is continually monitored for external threats that may appear at the host or application levels. At the same time, all data in transit to and from Splunk Cloud is encrypted using secure socket layer (SSL) encryption, protecting all data between the web server and the browser.

In addition, Splunk manages application security – monitoring the apps to ensure they follow Splunk Cloud app best practices. Thus assuring the security of your data while complying with industry regulations.

A powerful platform to analyse your data

Enterprises choose Splunk for several reasons, from tracking unusual behaviours to mitigating threats to monitoring and troubleshooting system issues across the organisation. Whichever challenge is on your priority list. Splunk provides a centralized place to manage and analyse your data and create tailored dashboards.

Suppose you are looking for a powerful, best-in-class scalable analytics tool that is easy to use and enables you to collect, index, and search data in real time. In that case, you should explore Splunk’s broad spectrum of capabilities. You will be surprised at what you will find.

Make sense of the complexity.

Observability is the evolution of monitoring, allowing you to compile actionable insights from unexpected behaviours in dynamic systems. It will help you speed up troubleshooting, enhance user experience, increase productivity, and detect hard-to-reach issues.

To get the most out of observability for your organisation, however, you need to integrate the right tools to provide the feedback you want. This is where a trusted partner like Telstra can help you choose tools that will immediately benefit your business, build observability into your technology roadmap, navigate pricing models, and adopt an observability mindset.
