Why Large MSPs With 50+ Clients Are Choosing Phin
![]()
Key Points/TL;DR
- The best security awareness training platform for large MSPs should let your client base grow without your administrative workload growing with it. Phin’s MSP-first platform centralizes campaign management, onboarding, reporting, phishing analysis, and other security services across dozens or hundreds of clients.
- Large MSPs are using Phin to manage thousands of users with very little ongoing administration. Kelley Create deployed Phin to 6,400+ users across 148 clients in 24 hours with one team member and now spends close to zero hours per year managing its security awareness training program.
- Automation can dramatically reduce the technician time required to manage human risk at scale. Resonant Technology Partners deployed ongoing training to 3,000+ users across 57 clients in four hours and uses Phinbox IQ to save 50+ technician hours per week analyzing approximately 200 reported emails.
Managing security awareness training for two clients is relatively straightforward. Managing it for 10, 50, or 100 is a very different proposition.
Every manual task gets multiplied. Every campaign you need to recreate, report you need to generate, user you need to onboard, and phishing email your technicians need to investigate becomes part of a much larger operational workload. In fact, the working hours required can increase exponentially if you’re not smart about it.
The best security awareness training platform for a large MSP isn't necessarily the one with the longest feature list. It's the one that lets you deliver an effective service across dozens or hundreds of clients without your administrative workload growing at the same rate. That's a big reason why large MSPs are choosing Phin Security.
Why Large MSPs are Choosing Phin Security
For MSPs managing 50+ clients, Phin Security combines multi-tenant security awareness training, centralized campaign management, automated reporting, phishing analysis, and dark web monitoring in a platform built specifically around the way MSPs work.
That MSP-first approach means multi-tenant management and automation aren't afterthoughts; they're designed around the realities of delivering cybersecurity services at scale. And rather than simply taking our word for it, let's look at what MSPs managing 50+ clients are actually doing with the platform.
Manage Security Awareness Training Across All Your Clients at Once
Imagine you've got 60 clients who all need roughly the same core security awareness training. Traditionally, that could mean creating, configuring, and maintaining 60 individual campaigns. Then, somebody wants to make a change - have fun doing it another 59 times.
Phin's Shared Campaigns allow MSPs to create a security awareness training campaign once and deploy it across multiple client environments. Updates can then be made centrally rather than editing each tenant individually.
See how Shared Campaigns work.
That becomes more important as your MSP grows. A task that takes 10 or 20 minutes isn't much of a problem for one client. Multiply it by 50 or 100 and suddenly you've lost hours, days, and your will to live due to repetitive administration.
Resonant Technology Partners experienced exactly this problem with its previous provider. After moving to Phin, the MSP used Shared Campaigns to deploy ongoing training to more than 3,000 users across 57 clients.
The entire migration was ready to deploy within four hours.
Ethan Earl, Director of Automation at Resonant, estimated that the same process would have taken multiple weeks with KnowBe4. Once deployed, Resonant reported spending practically no time managing the platform outside of adding new users.
And Resonant isn't an isolated example. Kelley Create uses Phin to deliver security awareness training across 148 clients and more than 6,400 enrolled users, while spending close to zero hours per year managing SAT.
For a large MSP, that's the kind of scalability that matters. Whether you're managing 57 clients or 148, your workload shouldn't grow at the same rate as your client base. If your 51st client creates the same amount of work as your first, there’s an issue somewhere.
Onboard New Clients Without Turning It Into a Project
The same principle applies when your MSP wins a new client.
Growth is obviously good news, but every new customer also creates work. If adding them to your managed security services involves complicated configuration, contracts, campaign creation, and manual user management, success can quickly create its own operational bottleneck. Suddenly, sales and ops aren’t necessarily pulling in the right direction, and marketing is being told to stop pulling in so many leads! (Hopefully you have this problem.)
Phin is designed to make onboarding repeatable. Existing Shared Campaigns can be applied to new organizations, while integrations and automated user syncing reduce the amount of ongoing administration required as employees join and leave.
Kelley Create, for example, deployed 148 clients with over 6,400 end-users in just 24 hours. Not only that, but they only needed 1 team member to deploy and now manage the platform, which requires close to zero hours per year.
Another MSP, Secur-Serv, rolled Phin out to more than 1,000 users across 61 clients during its first year. Its implementation engineers worked alongside Phin on the initial deployment, documented the process, and created a standardized workflow that other technicians could then follow.
For MSPs growing organically or through acquisition, that repeatability is super valuable. You don't need to reinvent your SAT deployment every time your client count goes up.
Get the Reporting You Actually Need
More data doesn't automatically mean better reporting.
Large MSPs need enough visibility to demonstrate value, identify trends, support compliance requirements, and give clients meaningful information about their security posture. What they don't necessarily need is another administrative job extracting that information from an unnecessarily complicated platform.
Phin automates much of the reporting process and focuses on the metrics MSPs and their clients actually need. Resonant uses Phin’s automated reporting to keep customer leadership informed without adding another recurring task for its technicians. Secur-Serv's customers can access reports when they need them for compliance requirements, board meetings, or internal reviews, with the MSP able to step in when additional reporting is required.

The result is reporting that supports the service rather than creating more work to prove that the service is working.
Scale Phishing Analysis Without Scaling Your Headcount
There's another slightly ironic problem that can appear when security awareness training works: users get better at reporting suspicious emails.
That's exactly what you want them to do. Unfortunately, somebody then has to investigate those emails.
At scale, phishing analysis can become a significant drain on technician time. A manual investigation that takes 15 or 30 minutes doesn't sound catastrophic until hundreds of reports are arriving every week across dozens of clients.
Phinbox IQ automates much of that initial phishing analysis, bringing information such as AI-driven severity analysis, headers, sender information, and link analysis right into the technician's PSA. It also allows threats to be remediated across multiple tenants instead of forcing technicians to repeat the same process client by client.
See how Phinbox IQ works.
The results for large MSPs have been significant.
At Resonant, investigating a reported email previously took around 20 minutes. With Phinbox IQ, that dropped to approximately five. At around 200 reported emails per week, Resonant estimates it is saving more than 50 technician hours every week.
Certified CIO, which manages 59 clients, saw similar results. Its technicians reduced average triage time from 15 minutes to three, cutting engineering time by 80%. Almost all incidents can now be handled by L1 technicians with minimal escalation, freeing senior engineers for work that actually requires senior expertise.
Scaling phishing analysis suddenly doesn't have to mean scaling your payroll alongside it.
Get More From One MSP-Focused Platform

Large MSPs don't only have more users and clients. They usually have more tools, vendors, integrations, contracts, and dashboards to manage too.
Phin continues to expand what MSPs can deliver from within the same ecosystem.
Alongside security awareness training and phishing simulations, Phinbox IQ provides phishing analysis capabilities while Phin's Dark Web Monitoring continuously checks for compromised credentials associated with client domains.
Because these capabilities are built around a multi-tenant MSP workflow, teams can monitor and manage clients centrally rather than introducing another isolated process for every new security service.
That continued development has been particularly valuable for existing partners.
As Joel Chambers, Escalation Specialist at Certified CIO, puts it:
"Phin gave us initial flexibility, and since then, keeps adding and adding features while others really don't."
Ethan Earl at Resonant similarly highlighted the simplicity of the platform alongside the breadth of its functionality:
"It's very simple and self-explanatory... there are a lot of useful features that weren't in other solutions we looked at."
For an MSP operating at scale, simplicity and capability aren't opposites. The goal is having the capabilities you need without creating more work for the people responsible for using them.
Reduce Work Without Sacrificing Behavior Change
None of this efficiency matters if users aren't actually becoming more security-conscious.
Security awareness training ultimately needs to change behavior, not simply make administration easier or tick a compliance box. That's why Phin sources content from 7 different providers, ensuring end-users have access to topics and formats relevant to them.
And with Phin's "Learning Moments" providing real time feedback on phishing simulations, end-users aren't just getting punitive training. They're getting content that is immediate and relevant to them.
See how "Learning Moments" work.
Certified CIO has seen its overall phishing simulation click-through rate decrease by more than 21% between months three and 36 of using Phin, with some individual clients seeing even larger reductions.
Secur-Serv has also seen phishing simulation click rates decrease while delivering Phin to more than 1,000 users. The MSP reported a 4.3% decrease during its first six months, alongside a median training completion time of just three days.
The aim isn't to choose between security outcomes and operational efficiency. Large MSPs need both.
Make Every Client More Profitable to Manage
Ultimately, most of these benefits lead back to the same thing: doing less repetitive work per client.
Certified CIO provides a particularly good example. With its previous SAT platform, maintenance required several hours every month. With Phin, that dropped to around five minutes.
For an MSP with many customers on unlimited contracts, those hours have a direct financial impact.
As Chambers explained:
"Profitability per end-user has gone up just from Phin. We have a lot of clients on unlimited contracts, so we have to really look at tech time per endpoint."
That's the scalability equation large MSPs have to consider.
Adding more clients should increase revenue without requiring an equivalent increase in administrative work, technician hours, or headcount. Whether it's deploying training across 57 clients in four hours, saving more than 50 hours of phishing analysis every week, or spending almost no time maintaining SAT across a large client base, Phin is designed to make that possible.
Security Awareness Training Built to Scale With Your MSP
The requirements of a managed service provider change as it grows.
When you're responsible for 50+ clients, you need more than good security awareness training content. You need a platform that can deploy that content efficiently, onboard new organizations quickly, automate reporting, handle growing volumes of reported phishing emails, and help your team deliver measurable security improvements without multiplying its workload.
That's why large MSPs are choosing Phin Security.
