What MSP Security Services Should Every Professional Services Firm Have?

Every professional services firm with 25–75 employees should expect their Managed Service Provider (MSP) to deliver at least 8–12 core security services as part of a standard managed IT offering. In the Oakville and GTA West market, firms typically investing $200–$250 per user per month should not be purchasing cybersecurity as a collection of add-ons. Foundational security controls should be built in by default.



When these baseline protections are missing, firms face a higher risk of ransomware, data breaches, failed cyber-insurance renewals, and extended downtime. Below is a practical, non-technical framework outlining the security services every professional services firm should require from an MSP—based on CIS and NIST best practices, not vendor hype.

1. Managed Endpoint Protection and EDR

Every device accessing firm data—laptops, desktops, and servers—must be protected with more than basic antivirus.

At a minimum, your MSP should provide:

• Centrally managed endpoint protection
  
  
• Endpoint Detection and Response (EDR)
  
  
• Continuous monitoring and alerting
  
  
• Automated isolation of compromised devices
  
  

EDR goes beyond detecting known malware. It looks for suspicious behavior, lateral movement, and early indicators of ransomware. Without it, many firms only discover issues after damage has already occurred.



If endpoint protection is optional or treated as an upgrade, that’s a red flag.

2. Firewall Management and Network Security

Firewalls are still a critical line of defense—but only if they are actively managed.

Your MSP should:

• Standardize on a small number of enterprise-grade firewall vendors
  
  
• Actively manage firewall rules and configurations
  
  
• Apply firmware updates and security patches regularly
  
  
• Monitor traffic for intrusion attempts and anomalies
  
  

When MSPs support many different firewall brands, expertise gets diluted. Standardization allows deeper knowledge, faster response, and fewer configuration mistakes—ultimately reducing risk for clients.

3. Identity and Access Management (MFA Everywhere)

Stolen credentials remain one of the most common causes of breaches.

Every professional services firm should expect:

• Multi-factor authentication (MFA) for email, cloud apps, VPNs, and administrative access
  
  
• Conditional access policies based on risk and location
  
  
• Regular reviews of user access and permissions
  
  

MFA should not be limited to “important users” or executives. It should be applied consistently across the organization, especially where sensitive client data is involved.

4. Email Security and Phishing Protection

Email remains the primary attack vector for most organizations.

Your MSP should include:

• Advanced spam and phishing filtering
  
  
• Attachment and link inspection or sandboxing
  
  
• Impersonation and domain spoofing protection
  
  
• Ongoing tuning based on emerging threats
  
  

Professional services firms are frequently targeted with highly convincing phishing attempts, often designed to impersonate clients, vendors, or internal leadership. Strong email security dramatically reduces successful attacks before users ever see them.

5. Backup, Disaster Recovery, and Ransomware Protection

Backups are not optional—and not all backups are created equal.

A mature MSP security offering should include:

• Automated, monitored backups
  
  
• Off-site or cloud-based storage
  
  
• Protection against ransomware tampering (immutable backups)
  
  
• Regular testing and verification of backup success
  
  

Firms should also understand their RPO (Recovery Point Objective) and RTO (Recovery Time Objective). In practical terms: how much data could you lose, and how quickly could you be back online after an incident?

If backups are rarely tested, they are not reliable.

6. Security Monitoring, Logging, and Alerting

Security tools alone don’t provide protection—people and process do.

Your MSP should:

• Collect logs from endpoints, firewalls, and cloud platforms
  
  
• Correlate events across systems
  
  
• Review alerts with human oversight, not just dashboards
  
  
• Actively respond to suspicious activity
  
  

This continuous monitoring helps identify threats early, often before users are aware anything is wrong.

7. Security Policies, Standards, and Framework Alignment

Professional services firms increasingly need to demonstrate security maturity—not just claim it.

Your MSP should help align your environment with:

• CIS Critical Security Controls
  
  
• NIST Cybersecurity Framework
  
  

This doesn’t mean implementing every control immediately. It means:

• Establishing a baseline
  
  
• Documenting policies and procedures
  
  
• Showing progress over time
  
  

This alignment is especially important for cyber-insurance renewals, client security questionnaires, and regulatory expectations.

8. Ongoing Security Reviews and Continuous Improvement

Security is not a one-time project.

Your MSP should provide:

• Quarterly or regular security reviews
  
  
• Visibility into risk trends over time
  
  
• A roadmap for improving security maturity
  
  
• Clear explanations in business terms, not jargon
  
  

The goal is continuous improvement—reducing risk year over year, not reacting to the latest headline breach.

Real-World Example: Security Built In vs. Security Added On

A 50-employee professional services firm previously worked with an MSP that provided basic antivirus and unmanaged firewalls. MFA was optional, backups were rarely tested, and security discussions were mostly reactive.

After switching to a security-first MSP model with standardized tools and built-in controls:

• MFA coverage increased from approximately 30% to 100%
  
  
• Backup success rates reached 99.9%
  
  
• Cyber-insurance renewal was approved without exclusions
  
  
• No successful phishing incidents occurred over the following 12 months
  
  

The firm didn’t become “perfectly secure,” but it moved from uncertainty to measurable, defensible security.

Why “Security as an Add-On” Usually Fails

Many MSPs still sell security as a menu of optional upgrades:

• Antivirus: extra
  
  
• MFA: extra
  
  
• Monitoring: extra
  
  
• Backup testing: extra
  
  

This approach creates gaps, complexity, and confusion. It also leaves leadership believing they are secure—when they may not be.



For professional services firms, security should be part of the foundation, not an upsell.

What Professional Services Firms Should Expect at This Price Point

At $200–$250 per user per month, firms should reasonably expect:

• A standardized, security-first technology stack
  
  
• Core CIS and NIST controls included
  
  
• Predictable costs without constant add-ons
  
  
• Ongoing monitoring, review, and improvement
  
  

Anything significantly less often signals a reactive model or limited security depth.

Trust Signals to Look For in an MSP

When evaluating MSP security capabilities, look for:

• Clear alignment with CIS and NIST frameworks
  
  
• Standardized security tools across clients
  
  
• Proactive monitoring and human oversight
  
  
• Regular security reviews with leadership
  
  
• Experience supporting firms similar to yours
  
  

Security isn’t about buying more tools—it’s about building a system that reduces risk over time.
