Security orchestration, automation and response – guide, tools and solutions.
What is SOAR?
SOAR (security, orchestration, automation and response) refers to software that allows organizations to streamline security operations across many areas, including threat and vulnerability management, incident response and security operations automation.
Security orchestration: connecting security tools and integrating disparate security systems.
Security automation: executing security operations-related tasks, such as retrieving new alerts, offenses and search results from security information and event management (SIEM) or indicators of compromise (IoCs) from threat intelligence, without human intervention.
Security response: a structured multi-step process that allows organizations to avert or reduce the effects of cyberattacks and data breaches.
What is a SOAR system used for?
SOAR platforms and solutions work by collecting data from a variety of sources, such as log files, application metrics, and cloud monitoring services, and then analyzing that data to detect anomalies that could be signs of a breach. Then, SOARs help teams plan and execute a response strategy for the identified threats, speeding threat detection and remediation through automation.
Automating time-consuming tasks is the most important feature of SOAR solutions, according to 57% of security professionals surveyed by Sumo Logic.
With an effective SOAR solution, achieving more in less time is possible while still allowing for human decision-making when it’s most critical. SOAR helps teams move beyond relying on point-to-point integrations. Instead, SOAR tools build out various processes to connect the right people and technology to achieve goals.
Altogether, SOARs provide an end-to-end security solution for modern businesses.
How do you implement SOAR solutions?
A critical factor to the success of SOAR tools orchestration capabilities is having a library of plugins for the most-used technology and a set of pre-built workflows for common use cases.
Typically, these workflows come in the form of customizable playbooks or runbooks based on industry standards and current best practices. They cover a broad spectrum of scenarios, from phishing to brute-forcing, to ransomware attacks. Equally important, playbooks allow you to automate a significant portion of the incident response lifecycle.

A wide range of plugins or integrations, along with pre-built playbooks, enables teams to easily connect your technology stack and automate your security and IT processes. You will likely need to build additional orchestrations or workflows customized to your team, but having pre-built examples and easy-to-use building blocks to work from should help accelerate the process.
Security threats are increasingly complex as attackers adopt techniques designed to obscure their activities. For example, they may use virtual machines to launch exploits, a practice that makes attacks harder to detect because metrics from the targeted machines don’t change until after the attack has already occurred. In other scenarios, malware may actively shut down a system’s security processes, preventing conventional security tools from discovering its presence.
As threats become more and more complex, SOARs provide deeper and more comprehensive security analytics to help diagnose and resolve threats faster. With a SOAR solution, companies can automatically collect more data and intensively analyze it to highlight threats and speed investigation activities.
The growing scale of cybersecurity threats and alerts
At the same time that threats are growing more complex, they are also increasingly pervasive. 2021 set records for the scope and frequency of cyberattacks, and 2023 is undoubtedly on track to do the same.
Subsequently, security teams have to respond to more alerts than ever. So-called alert fatigue is one of the most persistent challenges for security teams. They struggle to keep up with the volume of alerts and discern between false positives and negatives and which alerts to prioritize.
False positives and alert fatigue were some of the issues Sumo Logic identified in a survey of security professionals.
SOARs address these challenges by providing contextualized, actionable information about security threats from a variety of different tools. Instead of merely identifying risks, SOARs categorize them based on their threat level. In many cases, SOARs offer guidance on how teams can most efficiently respond to a threat. And as we’ve noted, SOARs can automatically remediate certain threats in some scenarios by orchestrating traditional security tools.
Cybersecurity skills shortage
Complicating the scale of modern threats is the fact that engineers qualified to respond to them are in short supply.
Even the smallest cybersecurity teams can lean on SOAR tools to handle threats. SOAR automates complex security workflows while helping all necessary stakeholders to coordinate their security response activities.

Can organizations replace SOAR with SIEM?
Historically, organizations have relied on SIEM to detect threats, but that’s where its functionality typically ends.
In contrast, SOAR orchestrates security responses to make threat intelligence actionable. With SOAR, you can coordinate disparate technologies — including third-party endpoint security providers, external threat intelligence feeds and other external tools to work together.
Many businesses leverage both for a more complete threat management solution.
Top benefits of SOAR solutions
SOAR helps build workflows and streamline operations
By adopting SOAR, businesses gain a variety of benefits that other types of security tools just don’t deliver.
Streamlined security response and automation
By making all data about security threats available to all stakeholders, and helping orchestrate response activities, SOAR eliminates the need to guess or take an ad hoc approach to threats.
In turn, SOAR helps to minimize the time it takes to contain and remediate threats – which is critical, given that active breaches can cost millions of dollars per minute.
SOAR provides enhanced alert management to help SOC teams
SOAR helps SOC teams make better sense of security alerts to improve their overall security posture. With a SOAR, it's possible to immediately see which systems are affected by a threat and determine the severity of a cyber threat without having to investigate it manually. It’s also easier to identify alerts that are likely false positives.
Sumo Logic Cloud SOAR takes a proactive approach to alert investigation.
Usually, a legacy SIEM makes alert triage an arduous task carried out by security analysts handling an overwhelming number of alerts. Sifting through the incoming data to separate positives from false alerts, prioritizing alerts, converting them to incidents, prescribing the optimal incident response and coordinating incident response activities is incredibly time-consuming. Moreover, regardless of how diligent security analysts are, mistakes can happen, resulting in missed threats that cause havoc on organizations.
SOAR automation
One of the fundamental advantages of SOAR platforms is automating and orchestrating the triage process. SOARs can automatically deal with exabytes of data, employ a stack of tools, and unify diverse processes to sharpen decision-making and perform alert investigation, enrichment and threat detection. SOARs execute triage much faster and more efficiently than humans, especially if a machine learning engine powers the SOAR. The benefits of SOAR automation include:
In these ways, SOARs enable more efficient alert management. Rather than attempting to handle each security alert as it comes in, teams empowered with SOAR can react proactively and strategically based on the severity of each alert and the scope of affected resources.
SOAR can integrate disparate tool sets
SOARs are not a replacement for existing security tools, but they can help to unify them by serving as a centralized platform for collecting, analyzing, and reacting to security-related data.
32% of security professionals require 6-10 tools to respond to a single security incident. SOAR acts as a connector, helping to centralize security operations around a single platform.
Without a SOAR, you would likely need to juggle a slew of different tools – such as log aggregators, metrics collection services, SIEM, threat intelligence, firewalls, IDS, IPS, EDR, IT services, ticketing system, IAM, analytics and monitoring, sandbox, XDR, email and web gateway, proxy, URL filtering, vulnerability management, IoT Monitoring, CASB, OT security tools, and so on – to stay on top of security threats. A SOAR functions as a common connector for all these tools, allowing you to centralize security operations around a single platform.
Lower costs with SOAR systems
Ultimately, SOARs can lower costs in two ways.
First, they reduce the time engineers spend manually identifying and responding to security threats. This translates to lower staffing costs.
Second, by reducing the time it takes to contain and remediate a breach, SOARs can help minimize the financial impact of cybersecurity events. SOAR platforms also help to reduce the amount of data exposed during a breach, which protects business reputation and may help to avoid regulatory fines. It’s commonly thought that cybersecurity teams are the only ones responsible for cyber attacks, but this is not true. Cybersecurity awareness has room for improvement. Every department that develops projects without considering cybersecurity puts its entire company at risk.
Increased flexibility, extensibility and collaboration across security teams
Although security teams may be the primary users of a SOAR, security analysts alone can rarely remediate an issue. Chances are, an organization uses technology multiple teams need to touch and collaborate on, yet the various pieces don’t always integrate. For example, if the root cause of a threat is a code vulnerability, they will need to work with developers to fix it. If it’s a configuration issue with an application or cloud service, they’ll need help from IT engineers. SOARs ensure that developers, IT engineers and other groups who need to be looped into the process can collaborate readily to achieve a speedy, effective response tracking every phase and related time.
Choosing the best SOAR solution
Whether you’re new to SOAR or you’re looking to change your current SOAR vendor, it’s important to align the needs of your security operations teams with the right SOAR solution. Since SOAR can significantly impact the security operations center (SOC), it is essential to understand the available options to make the best decision for the right SOAR solution. Whether adapting workflows, creating and managing integrations, or building entirely new processes, it’s essential to understand how to compare SOAR solutions and vendors. Here are the criteria for finding the best SOAR solution:
