What is an MSSP?

A Managed Security Services Provider (MSSP) is a specialized cybersecurity services provider that offers outsourced monitoring and management of security devices and systems to businesses. Common services offered by MSSPs include managed firewall, intrusion detection, virtual private network, vulnerability scanning and antiviral services.

A Managed Security Service Provider (MSSP) provides outsourced monitoring and management of security devices and systems. An MSSP will remotely monitor network security events and send alerts to your team if they notice any anomalies. MSSPs deliver continuous security monitoring and asset management, so they’re typically best used for threat prevention. With an MSSP, you can get the benefits of the latest monitoring technology without having to acquire, configure, and monitor it yourself.

MSSPs also augment your internal security team by monitoring security events 24/7, helping reduce the impact and cost to your company. This allows you to focus your internal cybersecurity resources on cyber threats that are more likely to become legitimate security incidents.

MSSP Differentiators and Limitations

Managed Security Services Providers (MSSPs) can play a critical role in enhancing your organization's cybersecurity posture. However, it's crucial to gain a comprehensive understanding of their differentiators and limitations before deciding to outsource your security to an MSSP.

MSSP Differentiators

1. Expertise and Resources
   MSSPs bring a team of skilled cybersecurity professionals with diverse knowledge and experience. Partnering with MSSPs allows you to fill your in-house cybersecurity skills gap and free your internal team to focus on the day-to-day business operations.
   
   
2. Advanced Technologies
   MSSPs have access to the latest tools and technologies that enable them to monitor and detect threats. An MSSP can also provide guidance on what solutions best fit your organization’s needs and assist with setup and configuration.
   
   
3. 24/7 Monitoring
   MSSPs often use a 24/7 Security Operations Center (SOC) to provide continuous monitoring and ensure potential threats are identified and addressed promptly.
   
   
4. Cost Efficiency
   Outsourcing cybersecurity to an MSSP can be cost-effective compared to maintaining a 24/7 in-house security team. Additionally, thanks to the scalability benefits available to MSSPs, they can equip your security team with advanced solutions at a reduced cost.

MSSP Limitations

1. Increased alert fatigue
   Most MSSPs only provide security monitoring and alerting, inundating your team with security alerts and false positives. The resulting alert fatigue can cause more strain on your in-house team, which may be already stretched thin.
   
   
2. Automated communication
   MSSPs often rely on a faceless portal to communicate with your team. In many cases, this isn't enough for security leaders who want more human involvement and expertise from their security providers.
   
   
3. Lack of complete response
   Most MSSPs simply send alerts about potential threats, so your team will still have to conduct threat investigations and remediate incidents in-house. Without appropriate tooling, security expertise, and threat intelligence, your team may be unable to conduct a complete threat response, leaving you open to attackers.
   
   

   “A CISO absolutely needs to value fast and accurate response, but what I’ve found is that not enough security leaders truly understand that the accuracy of the response is powered by the maturity of the threat investigation. As a security leader, you must question how can the vendor respond to a threat if they haven’t done the necessary legwork for the threat investigation portion?”
   - Tia Hopkins, Chief Cyber Resilience Officer & Field CTO, eSentire

4. Reactive approach
   Many MSSPs don’t take proactive measures within their threat hunting or threat intelligence programs. As a result, your security team will need to take reactive measures to address cyber threats that have already penetrated your environment or progressed to hands-on intrusion.
   
   

In summary, MSSPs are typically best used for threat prevention, so you get the benefits of the latest monitoring technology without having to acquire, configure, and monitor it yourself.

However, if you’re looking for threat detection, hypothesis-driven threat hunting, deep investigation and response to threats on your behalf, you need to be aware of the limitations MSSPs may have.

How to Choose a Managed Security Services Provider

Choosing the right Managed Security Services Provider (MSSP) is a significant decision that can greatly impact your organization's cybersecurity posture. Navigating through this process comes with its own set of challenges that require careful consideration and evaluation.

What Should You Include in an MSSP RFP?

Crafting a thorough and well-structured Request for Proposal (RFP) is an essential in the evaluation cycle of Managed Security Services Providers (MSSPs. An effective RFP sets the stage for transparent communication, informed decision-making, and a successful partnership.

Clearly Defined Security Goals

Start by articulating your organization's security objectives. In the ever-expanding threat landscape, compliance adherence is rarely enough to anticipate, withstand and recover from sophisticated threats. Instead, focus on meaningful risk reduction and strategies that help you build long-term cyber resilience. Having clear security goals will help potential MSSPs understand the outcomes you seek from their services.

Compliance and Regulatory Requirements

Every year, new compliance regulations and frameworks are introduced globally. Whether HIPAA, PCI DSS, NIS2, Essential Eight, or other industry-specific standards, your MSSP provider should play an integral role in helping you achieve compliance and demonstrate adherence to compliance standards.

Scope of Services

Detail the specific services and capabilities you expect from a security provider in your MSSP RFP. This could include around-the-clock monitoring, advanced threat detection, complete incident response, regular vulnerability assessments, etc. If any third-party software or subscription services are required, ask your short-listed MSSPs to include these in this assessment. Clearly defining the scope helps the MSSP tailor their proposal to your organization's needs, avoiding misunderstandings later.

Technical Infrastructure

Alignment with your current security tools and system with technology solutions provided by MSSP is crucial for seamless integration. If you have existing security tools and systems, ask your potential MSSP to specify how their solutions will integrate with your existing infrastructure. This helps ensure their technology stack can provide full visibility across your attack surface and minimize setup challenges.

Reporting and Metrics

It’s crucial that you gain an understanding of how the provider will report on the efficacy, how often they will deliver the reports, how much visibility you will have into the health of your environment, and how your KPIs compare against those of your industry peers. Outline the reporting and metrics you require in your RFP. This will allow potential MSSPs to demonstrate how they measure and communicate their impact.

Budget and Pricing Structure

While not all MSSP RFPs include budget details, providing a budget range or understanding of your financial constraints can help potential MSSPs tailor their proposals accordingly. Ask to see the pricing model of each component of the service package to evaluate the value proposition and align the services to your organizational priorities. In addition, inquiring about discount rates for longer-duration contracts can help discover cost-saving opportunities.

Timeline and Expectations

Including timeline considerations in your MSSP RFP is essential. If you have a desired start date and critical service implementation milestones indicate them in your RFP. Request a proposed timeline for rollout, setup and deployment to align expectations and plan accordingly.

Modern threats can move to a hands-on intrusion phase in minutes, so consider any Incident Response time commitments your MSSP may have. If an incident occurs, you will need to have confidence that your security partner can rapidly contain threats, restore your systems and minimize business disruption.

Evaluation Criteria

Define how you evaluate the MSSP proposals. Whether based on technical capabilities, experience, references, cost, or a combination of factors, outlining your evaluation criteria ensures a fair and consistent assessment.

By crafting an MSSP RFP that covers these essential elements, you will set a foundation for meaningful proposals that potential providers can address effectively.

MSSP vs. MDR: Key Differences Between MDR and MSSP

Given the limitations of traditional MSSPs, engaging a Managed Detection and Response (MDR) provider can be an effective way to build resilience, prevent business disruption and reduce downtime.

MDR focuses on delivering 24/7 threat detection, investigation, and response capabilities by ingesting multiple signals across endpoint, network, log, cloud, identity, and vulnerability sources. This multi-signal capability is crucial to maintain full visibility across your entire attack surface and rapidly contain threats – simply monitoring endpoints and network is no longer enough.

Unlike legacy MSSPs, MDR providers offer a more tailored approach to security, eliminating false positives, identifying real threats and helping remove the burden on your internal resources through automated threat blocking and expert-led threat response. 

Is an MSSP Right for You? Or Should You Turn to MDR?

Deciding between an MSSP and MDR provider depends on your organization's security needs, risk tolerance, and long-term goals. If you’re looking to respond to known and unknown advanced threats fast, minimize the risk of business disruptions and alleviate resource constraints, a true MDR provider will help you maximize the ROI on your investment and deliver stronger security outcomes than a legacy MSSP.

By taking on threat containment and response capabilities, MDR providers deliver greater value to IT teams that are unable to hire, train, and retain highly skilled and certified 24/7 cybersecurity staff.
