Is Your MSP Cyber Security the Weak Link? How to Secure Your Stack
Did you know that 60% of managed service providers (MSPs) experienced a cyberattack in the past year? That’s a staggering number — and it highlights a growing issue in the world of cybersecurity.
MSPs are supposed to protect businesses. But sometimes, they unintentionally become the weakest part of a company’s security setup. Old tools, sloppy configurations, or poor planning can leave big gaps in protection. And when cybercriminals break through, they don’t just hurt one company — they hit dozens or even hundreds of clients connected to that MSP.
This blog breaks down why MSPs are such tempting targets for attackers, where their security stacks usually fall short, and what steps they can take to tighten things up. Whether you’re new to the industry or a seasoned IT pro, these tips will help you boost your MSP cyber security and protect your entire ecosystem.
Why MSPs Are Prime Targets for Cyberattacks
Let’s understand why MSP is the major target of cyberattacks:
The Expanding Attack Surface
MSPs manage loads of systems. That means more entry points for cybercriminals to attack. Recent supply chain attacks, like those on Kaseya and SolarWinds, show that hackers are targeting MSPs to launch vast attacks. It’s a strategy built on deception.
High-Value Data Access
MSPs hold the keys to the castle. Think admin credentials, sensitive data, and backups. That kind of access makes MSPs attractive to ransomware groups and other cybercrime organizations looking to make fast money or disrupt services.
Shared Responsibility Model Gaps
Many MSPs believe that clients will handle some parts of their own security. But that assumption often leads to major blind spots. Clear communication and shared expectations are essential in avoiding risky gaps in computer security.
Compliance & Legal Risks
Not securing your clients’ data isn’t just dangerous — it can also be illegal. Regulatory rules like GDPR, HIPAA, and CCPA mean MSPs could face major penalties. Data laws are strict, and failure to follow them can lead to lawsuits, lost trust, or even closure.
Common Weaknesses in MSP Security Stacks
Since you understand why MSP is a cybercriminal’s major target now explore its common weaknesses:
Poor Identity & Access Management (IAM)
Many MSPs still use shared admin accounts or reuse weak passwords. Without multi-factor authentication (MFA), hackers can easily slip in. In one real-world example, an MSP was breached just because one technician reused their password across platforms. A simple fix could’ve stopped it.
Unpatched & Outdated Software
Delayed updates are a hacker’s best friend. Vulnerabilities in Remote Monitoring and Management (RMM) tools, like ConnectWise Automate, have been widely exploited. Regular patching is key to crime prevention.
Insufficient Endpoint Protection
Traditional antivirus (AV) tools aren’t enough. Today’s threats need Endpoint Detection and Response (EDR) or Extended Detection and Response (XDR) to stay ahead of malware, ransomware, and other threats lurking in cyberspace.
Weak Backup & Recovery Practices
If you store backups on the same network as production systems, you’re risking everything. A ransomware attack could encrypt it all — including your backups. The lack of offsite or immutable backups has led to major MSP failures.
Misconfigured Cloud Services
Default settings in platforms like Azure or AWS are not secure. Exposed S3 buckets, wide-open access rights, and forgotten privileges all create holes. This is where secure communication and identity management really matter.
Lack of Employee Security Training
Your own team can be a gateway for hackers — especially through phishing, voice phishing, pretexting, or other social engineering tactics. If employees don’t understand how these tricks work, they could accidentally invite a threat actor in.
No Incident Response Plan
What happens after an attack? Many MSPs don’t have a plan. Without a response strategy, downtime stretches longer, costs climb, and clients lose confidence. In the Information Age, time equals reputation.
How to Strengthen Your MSP Security Stack
Finally, we explore the key areas to make MSP cyber security stronger:
Implement Zero Trust & Least Privilege Access
Don’t trust — verify. Enforce MFA across all systems. Use role-based access controls (RBAC) and privileged access management (PAM) to make sure users only see what they need to. This reduces exposure and strengthens access control.
Automate Patch Management
Automate updates for your RMM, PSA, and client environments. Tools like NinjaOne, Datto RMM, and Automate make this easy and efficient. Keeping software current closes the door on known exploits.
Upgrade to Advanced Endpoint Protection
Ditch outdated AV tools. EDR/XDR solutions like SentinelOne, CrowdStrike, or Microsoft Defender offer deeper insights and quicker reactions to cyber threats. This helps in early detection and secure communication.
Harden Backup & Disaster Recovery
Follow the 3-2-1 backup rule: three copies of data, on two different media types, with one offsite. Use immutable backups from providers like Veeam or Acronis. This ensures business continuity even after ransomware attacks.
Secure Your Cloud & SaaS Stack
Log every activity, audit permissions regularly, and use conditional access policies. Tools like Azure Sentinel and AWS GuardDuty help detect and respond to threats. Also, use Security Posture Management solutions to check for misconfigurations.
Train Your Team & Clients
Run regular phishing simulations and security awareness training. Use platforms like KnowBe4 or Proofpoint. Even a short session can help your team spot email spoofing, scam messages, or signs of cyber fraud.
Develop a Proactive Incident Response Plan
Have a step-by-step plan: detect, contain, eliminate, recover, and review. Consider investing in cyber insurance too. Planning ahead helps avoid panic when things go wrong.
Continuous Monitoring & Threat Hunting
Use SIEM tools like SolarWinds SIEM, Arctic Wolf, or Splunk to monitor activity 24/7. These help detect malware, scareware, or unauthorized access attempts in real time — and stop attacks before they spread.
Building a Culture of Security
Security isn’t just about tools. It’s about people and values.
- Leadership Buy-In: When leaders take security seriously, the rest of the team follows. Invest in training, tools, and secure technologies.
- Client Education: Teach clients the basics — like enabling MFA and avoiding phishing emails. Help them understand the shared responsibility model.
- Transparency: Share regular updates on threats, security efforts, and response plans. This builds trust.
- Stay Informed: Follow trusted frameworks like NIST CSF, MITRE ATT&CK, or CIS Controls. Keep learning about new threats and solutions in the ever-changing world of computer networking and cyberwarfare.
Conclusion
If you’re an MSP, your cyber security efforts don’t just protect you — they safeguard all your clients, too. This blog covered the main weak points many MSPs face, from poor access control to untrained staff, and offered ways to fix them. Remember, your reputation and your clients’ data are on the line.

FAQs
1: What is MSP cyber security?
It refers to the tools and strategies managed service providers use to protect their own systems and their clients’ data from cyberattacks, scams, and other threats.
2: Why are MSPs high-value targets for cybercrime?
MSPs have access to many clients’ networks and data. This makes them prime targets for organized crime and hackers looking to spread ransomware or steal sensitive information.
3: What is social engineering in security?
It’s when attackers trick people into giving up information or access. Common forms include phishing, voice phishing, and pretexting.
4: How can MSPs protect against phishing and email fraud?
Train staff regularly, use DMARC, SPF, and DKIM for email authentication, and monitor for email spoofing and spam.
5: What laws impact MSP cyber security?
Data protection and computer law like HIPAA, GDPR, CCPA, and the Gramm-Leach-Bliley Act impact how MSPs handle and secure personal data.
6: What tools can help secure MSP stacks?
Use EDR tools like SentinelOne, cloud security tools like GuardDuty, patch managers like NinjaOne, and SIEM tools like Splunk.
7: What role does employee training play in preventing cyberattacks?
It’s essential. Many breaches begin with human error. Training boosts awareness, reduces risks, and helps spot scams or signs of deception early.
