Do Managed IT Security Services Really Work?

Jun 26, 2024

Managed IT Security Services Providers (MSSPs) are specialized providers who remotely manage and monitor a company’s IT security infrastructure. As our dependence on digital systems grows, so too does the need for robust cybersecurity solutions. MSSPs are rapidly becoming an essential tool for businesses seeking to navigate the ever-evolving threat landscape.

The Effectiveness of These Services — Do They Work?

While Managed IT Security Services (MSSPs) offer a compelling solution, some businesses remain skeptical about their true effectiveness. Concerns linger around whether MSSPs can truly understand a company’s unique security needs and deliver a customized approach. Additionally, questions arise regarding the return on investment, with some unsure if the ongoing cost translates to a tangible reduction in security risks.

What Are Managed IT Security Services?

Managed IT Security Services (MSS), also known as Managed Security Service Provider (MSSP) services, refer to outsourcing your cybersecurity needs to a specialized third-party vendor. Their responsibilities can vary depending on the specific service package chosen but often include:

Security Monitoring and Analysis

Continuously monitoring your network activity for suspicious behavior and potential threats.

Security Event and Incident Response

Investigating security alerts, containing breaches, and taking steps to recover from incidents.

Vulnerability Management

Identifying and patching vulnerabilities in your systems and software.

Security Policy and Compliance Management

Developing and enforcing security policies to ensure compliance with regulations.

Security Awareness Training

Educating employees about cybersecurity best practices.

Tools, Technologies, and Methodologies

Tools

  • Security Information and Event Management (SIEM): This function aggregates data from various security tools, analyzes logs, and identifies potential threats in real time.
  • Vulnerability Scanners: Scans systems and applications for known weaknesses, allowing for timely patching and remediation.
  • Endpoint Detection and Response (EDR): Monitors individual devices (endpoints) for suspicious activity and enables rapid response to malware or unauthorized access attempts.
  • Network Security Tools: Firewalls, intrusion detection/prevention systems (IDS/IPS), and traffic monitoring tools form the first line of defense, filtering and blocking malicious network traffic.
  • Data Loss Prevention (DLP): Monitors data movement and prevents sensitive information from being leaked accidentally or intentionally.

Technologies

  • Encryption: Safeguards data at rest and in transit, rendering it unusable by unauthorized parties.
  • Multi-Factor Authentication (MFA): Adds an extra layer of security by requiring a second verification factor beyond a username and password.
  • Identity and Access Management (IAM): Controls access to systems and data, ensuring only authorized users have the necessary permissions.
  • Security Orchestration, Automation, and Response (SOAR): Automates repetitive security tasks, allowing for faster and more efficient incident response.

Methodologies

  • Threat Intelligence: Relies on threat intelligence feeds to stay updated on the latest cyber threats and adjust their security posture accordingly.
  • Penetration Testing: Simulates cyberattacks to help identify vulnerabilities and test the effectiveness of existing security measures.
  • Security Incident and Event Management (SIEM): Ensures a systematic approach to incident handling, minimizing damage and restoring normalcy.

Typical Providers of Managed IT Security Services and What Qualifies Them

Types of Providers

  • Security-Focused MSSPs: Offer cybersecurity, providing the highest level of expertise and advanced security tools.
  • Managed Service Providers with Security Services: Offer security services alongside their general IT management solutions.
  • Cloud-Based MSSPs: Leverage cloud-based security tools and expertise, offering a scalable and cost-effective solution for businesses with a cloud-centric infrastructure.

Qualifying an MSSP

  • Security Expertise: Look for a provider with a team of experienced security professionals holding relevant certifications (e.g., CISSP, Security+).
  • Security Certifications: Industry-recognized security certifications like SOC 2 or PCI DSS compliance demonstrate a commitment to robust security practices.
  • Technology Stack: Evaluate the tools and technologies offered by the MSSP to ensure they align with your specific security needs and threat landscape.
  • Compliance Expertise: If your industry has specific compliance requirements, choose an MSSP with experience in navigating those regulations.
  • Scalability and Flexibility: Select a provider that can adapt its services to your evolving security needs and business growth.

How Continuous Monitoring and Proactive Security Measures Work

MSSPs constantly watch your systems for suspicious activity using tools like SIEM and EDR. These tools identify potential threats like malware or unauthorized access attempts. Additionally, vulnerability scanning regularly checks for weaknesses in your software and systems, allowing for swift patching before they can be exploited. MSSPs prevent attackers from gaining a foothold in your network and significantly reduce the risk of a data breach.

Statistics — Businesses with and Without Managed IT Security Services

While there isn’t a single definitive study comparing breach statistics with and without MSSPs, there is strong evidence suggesting their positive impact:

High Breach Rates for Smaller Businesses

Studies by Verizon and StrongDM show that 43-46% of cyberattacks target businesses with less than 1,000 employees

Focus of MSSPs on Detection and Response

A study by IBM found that, on average, it takes companies 280 days to identify and contain a data breach.

Human Error as a Leading Cause of Breaches

According to CompTIA, 95% of breaches are caused by human error, often due to phishing attacks.

Costs of Services vs. the Cost of a Security Breach

Cost of MSSPs

MSSPs typically charge monthly or annual fees based on the complexity of your network and services required. Costs can range from a few thousand dollars to tens of thousands per month for larger organizations.

Potential Costs of Security Breaches

  • Direct Costs: These include data recovery, forensics, legal fees, credit monitoring for impacted individuals, and regulatory fines.
  • Indirect Costs: These include lost business due to downtime, reputational damage, and customer churn.

Misconceptions and Real Limitations of Managed IT Security Services

Misconceptions

  • Myth: MSSPs are a one-size-fits-all solution. Reality: Reputable MSSPs offer customizable service packages tailored to your specific industry, network size, and security needs. However, smaller businesses may need to choose a pre-defined package with a set of core functionalities.
  • Myth: MSSPs replace the need for in-house IT security staff. Reality: MSSPs are an extension of your security team, providing expertise and tools your internal staff might lack.
  • Myth: MSSPs guarantee complete security. Reality: No security solution is foolproof. However, MSSPs significantly reduce the risk of breaches through proactive monitoring, threat intelligence, and user education.

Limitations

  • Cost: MSSPs can be a significant expense, especially for smaller businesses. Carefully evaluate your security needs and budget constraints before committing.
  • Visibility: Choose an MSSP that provides clear reporting and regular communication to maintain a sense of control.
  • Integration: Integrating the MSSP’s tools and processes might require some initial effort. Ensure a smooth onboarding process with clear communication between your IT team and the MSSP.

Tips on Selecting the Right Managed IT Security Services Provider

References and Case Studies

Request references from existing clients and ask for case studies showcasing the MSSP’s success in resolving security challenges similar to yours.

A Robust System

Robust cybersecurity is critical to avoid data breaches. Managed IT Security Services (MSSPs) address this need by offering continuous monitoring, expert teams, and advanced tools to proactively identify and eliminate threats.

While not an absolute shield, MSSPs significantly reduce the risk of breaches, potentially saving businesses from devastating financial losses and reputational damage. As the cybersecurity landscape constantly evolves, MSSPs are becoming an increasingly important investment for businesses of all sizes.
