Want to learn more on how to achieve Cyber Resilience?



Over the past year we have witnessed some truly destructive cyber attacks occurring on a global scale. Although cybersecurity teams have tried their best to keep up with the onslaught of activity, threat actors have demonstrated their expertise in how they target and deploy cyber attacks time and time again. From the shift towards using a ransomware-as-a-service model to the use of tactical experts as a result of role differentiation within ransomware groups, cybercrime has evolved significantly.

As a result, many organizations are left scrambling to protect themselves against these inevitable cyber threats. Although large enterprises typically have the resources to manage cybersecurity programs in-house, small to mid-size enterprises (MSEs) don’t have this luxury. Due to the rising costs and recessionary pressures, security leaders are facing increased scrutiny around investments. According to a 2023 Forrester Consulting survey, 81% of security leaders are looking to consolidate security products and services in light of increased economic instability.

As a business leader, you must evaluate how to scale your existing IT operations with a combination of in-house and outsourced solutions, which will allow you to build cyber resilience. Outsourcing SOC operations can be an effective way of consolidating your tools and systems into a single point of control to quickly identify and contain threats in your environment. However, an in-house SOC offers direct control over your security environment and the ability to customize your defense strategy and tools. That may leave you asking yourself, “Should I build or buy SOC for my organization?”

What is a SOC and Do You Really Need One?

A modern Security Operations Center (SOC) is a facility where security analysts utilize forensic tools and threat intelligence to hunt, investigate and respond to cyber threats in real-time. According to Gartner, a modern SOC must have four capabilities: detection engineering, monitoring, incident response, and threat intelligence.

The role of the SOC is to protect an organization from known and unknown cyber threats that can bypass traditional security technologies. While every organization should have access to a SOC facility, not many have the resources required to build their own in-house SOC. In fact, a 2022 survey from Deloitte states that 81% of organizations outsource their cybersecurity operations.

So, now you must decide: should you build your own SOC in-house using your own staff, technology, and resources or should you outsource SOC capabilities by enlisting the help of a Managed Detection and Response (MDR) partner?

Are You Ready for an In-House SOC?

Building an in-house SOC facility isn’t an overnight decision. In addition to years of commitment into designing the facility, your cybersecurity team must consider the financial investment required to arming it with the best people, processes, and technology. By a conservative estimate, the costs associated with building a SOC in the first year alone for 1,000 employees can be upwards of $2.2M.

Considering the up-front and ongoing investment involved with building an internal SOC, a growing number of organizations have turned to a Managed Detection and Response (MDR) provider.

However, if you’re still thinking about building an internal SOC, start by asking these critical questions:

1. What is the annual budget you have allocated toward the SOC?

Another essential aspect to take into account is your budget. Establishing a Security Operations Center (SOC) can represent a substantial financial commitment, and it's crucial to determine your financial limitations.

The ongoing expenses and maintenance of an in-house SOC can be costly, so you need to have the financial and organizational buy-in for the project. Evaluate expenses related to equipment, software, personnel, and continuous maintenance.

Additionally, security leaders should consider the potential cost savings of outsourcing your SOC to a third-party provider. Outsourcing your SOC removes the need for building an in-house solution, investing in state-of-the-art security tools, and retaining cybersecurity talent.

2. Can your team of security analysts support 24/7 in-house SOC operations?

Small businesses are increasingly facing the same cyber threats as larger organizations. As a result, no matter the size of your organization, 24x7 monitoring and detection capabilities are necessary to fend off modern threats.

You may now ask yourself, “How much does IT cost to build a 24x7 SOC?” Although the idea of staffing a 24/7 in-house SOC may be daunting, keep in mind that around-the-clock coverage can be achieved by outsourcing SOC operations.

If you outsource your SOC operations, you have the option of splitting time with your SOC provider (i.e., your security analysts work from 8-5 while the provider covers your team outside of those hours) or simply rely on the provider for full 24/7 operations. The latter option also helps your team get access to expert analysts so you don’t have to worry about attracting and retaining skilled analysts yourself.

3. Who is going to design the SOC?

How do you build a successful SOC? First, you need to assess whether you have the skilled expertise necessary to design this in-house or the required budget to attract the right talent for the roles of multiple security analysts. Considering that building a SOC is a multi-year project, you need to be confident that you can retain the talent needed to see the project through from start to finish.

By leveraging an external SOC provider, your team can access a fully operational 24/7 SOC within weeks of deployment. Plus, you don’t have to plan for attracting and retaining the required expertise – your SOC provider shoulders that responsibility.

4. Who will document SOC processes and procedures?

There are governance, risk, and compliance frameworks you need to consider as you set up your internal SOC. You need to make these considerations prior to scaling your SOC operations, so it’s your responsibility to learn about the regulations facing your business or industry and map out your requirements from the very beginning.

5. How will you interpret and deliver threat intelligence insights?

Detection engineering is a key capability in a modern SOC, which requires that your team is able to innovate at the same pace as cyberattackers. On the other hand, an external SOC provider will afford you the expertise of a Threat Intelligence team to help correlate and enrich intelligence from daily SOC investigations to deliver key insights.

An added benefit of working with an external MDR provider is that you can take advantage of their robust customer base to drive further threat intelligence. Lastly, consider the importance of response times as part of your SOC operations. Without good threat intelligence or reduced SOC operational capacity, it can take several hours (even days) to detect and respond to threats.

Engaging an external MDR provider will drastically impact how fast a potential threat will be detected, investigated, and contained. What’s more is that your team will even get full incident response and remediation support with digital forensics capability.

6. How will you demonstrate value to the executive team and board of directors?

Since setting up a SOC is a multi-year commitment, you need to report on critical KPIs such as the Mean Time to Contain, Mean Time to Detect, number of threats disrupted, and the impact on the overall business is key to justify the investment and demonstrate its value.

On the other hand, if you work with an external SOC and MDR provider, it’s their responsibility to report on the key KPIs and metrics based on your business objectives and priorities so that you can convey the ROI to your executive team and the board of directors.

7. Do you have enough staff to build a SOC team?

Not only must your organization be able to attract the best security analysts, you must be able to retain them year after year and grow the team as your SOC operations scale. Attracting and training this talent may even impact your Time to Value.

However, with an external MDR provider, you have access to elite cybersecurity analysts 24/7. This means SOC deployment will take a few weeks at best compared to a months-long process if you’re building it in-house.

8. How are you going to engineer and deploy the technology required to run and manage the SOC?

Building an internal SOC requires multiple product purchases and vendor contracts. Moreover, your team will also have to integrate all the tools into a single solution. So, assess your tools, people, and skills to determine whether you have the expertise to evaluate and deploy these technologies in-house.

In comparison, an external MDR provider will have all the fully integrated technologies and skilled expertise in place, which can save your team time and resources.

9. What is the future of a SOC?

As the sophistication and scale of cyber threats grow, it becomes crucial for all organizations – large or small – to have dedicated cybersecurity experts who monitor and analyze security systems to provide proactive and reactive defense capabilities. Additionally, as SOC analysts grapple with an increasing volume of alerts, automation and AI technologies will play an important role in disrupting and containing threats in real-time.

Moreover, the SOC will evolve to adopt a proactive approach, focusing on threat hunting and predictive analytics to identify vulnerabilities before they can be exploited. Security teams and engineers will face the need to integrate security practices into DevOps processes. Ultimately, the future of SOCs will be marked by agility, innovation, and adaptability to meet the ever-evolving landscape of cybersecurity threats.
