Cyber security best practices for MSPs: a summary of the Guardz guide

The original article: The Ultimate Guide to Cybersecurity Best Practices for MSPs, published 20 May 2026 by the Guardz team. Full credit for the framework and arguments below sits with them. This piece is a summary with our commentary, not original analysis.

What the Guardz article covers

The Guardz guide makes the case that a modern managed IT provider cannot separate technical capability from business behaviour. Strong security tooling on its own is not the differentiator. Strong tooling in the hands of a provider who is proactive, communicative and genuinely invested in the client’s business is.

The piece organises around three threads: the qualities that distinguish good MSPs, the defensive practices that need to be in place underneath, and the operational habits that turn cyber security into part of a sustainable client relationship rather than a project that ends after deployment.

The qualities that matter

The guide opens with a familiar but worth-repeating set of qualities that separate a competent MSP from a transactional vendor:

• A proactive approach to IT management, rather than waiting for tickets to surface problems
• Deep understanding of various IT systems, not just the headline tools but the way they integrate
• Flexibility to scale with the client as the business changes
• Communication discipline that keeps the client informed without overwhelming them

None of these are revolutionary. The point is that they are prerequisites, not differentiators. Without them, the rest of the security work does not land.

The defensive practices

On the technical side, the guide reinforces the controls that most SMB-focused security frameworks (including SMB1001 and the ASD Essential Eight) already prioritise:

• Regular security assessments rather than a one-off project at the start of the relationship
• Layered defensive tooling: antivirus is no longer enough on its own, EDR and a comprehensive cyber security platform are now baseline
• Continuous infrastructure monitoring, not point-in-time checks
• Disciplined patching, with software kept current and known vulnerabilities closed quickly
• Disaster recovery and backup planning, tested not just configured

The framing the article uses, that the most useful description of cyber security in 2026 is "24/7 detection and response", lines up with how AgileSECURE is built. Detection without response is just an alert log nobody reads.

The operational habits

Where the guide is at its strongest, in our view, is on the operational side. The argument is that what makes cyber security work over time is not the deployment, it is the routine around it:

• Continuous training, for the MSP’s own team and for the client’s. Capability has a shelf life
• Understanding the client’s actual business, not just the technology under it. Security decisions follow business decisions, not the other way around
• Holistic cyber security platforms, rather than stitched-together tools, to reduce the operational overhead that erodes coverage over time
• Demonstrating measurable value through reporting, so the client can see what the security investment is actually doing
• Staying current with industry trends, because attacker techniques evolve faster than any single product can keep up with

Where this lines up with how Agile IT works

The themes in the Guardz guide are not new to us, but seeing them written out as a coherent framework is a useful exercise. A few specific overlaps with how Agile IT delivers cyber security:

• We have aligned AgileSECURE to the SMB1001 framework precisely because a named framework forces discipline that a best-effort approach does not
• We chose Guardz Ultimate as the security overlay for Microsoft 365 in part because of its continuous validation of detection coverage, the "is the EDR actually working" question from their earlier Be the Purple piece
• Our AgileCOMPLETE tier includes quarterly business management reviews, which is the cadence the Guardz guide recommends for keeping security aligned to where the business is actually going
• The reporting layer in NinjaOne and HaloPSA is the practical answer to the article’s point about demonstrating measurable value through reporting, with clients able to see their environment status through the client portal

What we would add

A small addition from our side, because the Guardz piece is written for an MSP audience and the client perspective is implicit: the single most useful question a business can ask its IT provider is not about a tool, it is about a cadence.

"How often do we meet to talk about cyber security strategically, not reactively?" If the answer is "when something happens", that is the gap. If the answer is "every quarter, with documented outcomes", that is closer to what the Guardz guide is describing.

Cyber security tools without that cadence drift. Cyber security tools with that cadence stay tuned.

The full Guardz article is worth the 10 minutes. It is written for an MSP audience but is readable by any business owner who wants to understand what their managed IT provider should be doing on the security side.
