Why Pen Tests Aren’t Always Enough

Why Penetration tests aren't enough
August 8, 2024

IT departments are the backbone of every organization, responsible for managing daily challenges that are critical to operations. But, as an IT professional, you can’t and shouldn’t be expected to do everything, including cyber security. Security has become a highly specialized domain. Hiring dedicated cyber experts is often beyond the budget of many businesses, leaving IT departments to shoulder the burden.

One of the most popular cyber tools that IT departments utilize is penetration testing (pen testing). While pen tests serve an important purpose by identifying vulnerabilities, they provide only a snapshot of security at a specific point in time. Pen tests are best used by companies who have already reached their desired security level, but who want to assess firewall weakness, password strength, server misconfiguration, and web application vulnerabilities.

In contrast, managed security services (MSS) offer continuous protection, adapting to the constantly changing threat landscape and ensuring ongoing network security.

You might be thinking, “Great, a blog telling us to hire outside experts who will show us up.”

We get it. And that’s where we’re a little different. Our job is to make your job easier and your business secure, collaborating with and respecting your internal IT team.

So, let’s move on to the advantages that MSS can deliver compared to relying on pen tests.

Continuous Monitoring and Proactive Threat Detection

As we mentioned, one-time penetration tests, while valuable, are akin to taking a photograph of your network’s security. They reveal vulnerabilities that exist at the time of the test but can’t account for new threats that emerge afterward. Managed security services provide ongoing monitoring, allowing for real-time detection and response to threats. This proactive approach ensures that vulnerabilities are identified and mitigated before being exploited.

Key Benefits:

  • 24/7 Monitoring: Constant vigilance against cyber threats.
  • Real-Time Alerts: Immediate notifications of suspicious activities.
  • Incident Response: Swift action to neutralize threats as they arise.

Comprehensive Security Coverage

A pen test identifies vulnerabilities within a specific scope, often limited by budget and time constraints. Managed security services offer comprehensive coverage, addressing not just the immediate vulnerabilities but also implementing long-term security strategies. This approach encompasses various aspects of cybersecurity, including firewall management, intrusion detection, endpoint protection, and more.

Key Benefits:

  • Holistic Protection: Coverage across all network entry points.
  • Layered Security: Multiple defensive measures to thwart different types of attacks.
  • Ongoing Improvement: Continuous updates and improvements to security protocols.

Cost Effectiveness

While a penetration test might initially seem like a cost-effective solution, it can end up being more expensive in the long run. If new vulnerabilities are discovered after the test, additional tests and mitigation efforts will incur extra costs. Managed security services spread the cost over time, providing consistent protection and reducing the likelihood of expensive breaches.

Key Benefits:

  • Predictable Costs: Regular, predictable subscription fees.
  • Reduced Risk: Lower likelihood of costly breaches and downtime.
  • Value for Money: Comprehensive service package often more economical than multiple one-off tests.

Expertise & Support

Without a dedicated cybersecurity team, it can be a time-consuming challenge to keep up with the latest threats and mitigation strategies. With managed security services, you have direct access to security experts who are well-versed in current cyber threats and defense mechanisms. This support ensures that your network benefits from the latest knowledge and technologies in the field. It’s an extension of your team.

Key Benefits:

  • Access to Experts: Benefit from specialized knowledge and skills.
  • Training and Education: Ongoing training for your IT staff on best practices.
  • Peace of Mind: Assurance that your network is under the watchful eye of professionals.

Regulatory Compliance

Many industries are subject to stringent regulatory requirements regarding data protection and cybersecurity, including Cybersecurity Maturity Model Certification (CMMC). One-time penetration tests might not be sufficient to meet these ongoing compliance needs. Managed security services ensure that your organization remains compliant with relevant regulations by continuously monitoring and adjusting security measures.

Key Benefits:

  • Ongoing Compliance: Regular assessments and adjustments to meet regulatory standards.
  • Audit Readiness: Preparedness for audits with continuous documentation and reporting.
  • Avoid Penalties: Minimize the risk of non-compliance fines and sanctions.

Next Steps

As an IT leader, you’re juggling a lot – keeping systems running smoothly, supporting your team and employees, and ensuring your company’s data is secure. It’s a tough job, and the last thing you need is to worry about emerging cyber threats. While a one-time pen test can provide a useful snapshot of your network’s security, it falls short of offering the comprehensive, continuous protection that managed security services deliver.

Deciding whether to outsource your organization’s IT security or keep it in-house is a significant decision, and we get that. If you’re ready to partner with an ally who respects and complements your IT team, or if you want to learn more, contact us today.
