Chicago IT Provider Score Dimensions: Spread
Chapters
Disclosure: this site is owned and operated by XL.net, a Chicago MSP that is itself ranked here. How we handle that conflict.
Which score dimension separates Chicago firms most?
Client Reputation, by a clear distance. Across the Managed Service Providers (MSPs) we scored on it, the middle half runs from 18.9 to 72.1, with a median of 35.3 and a mean of 44.4, and it is scored for 94 of 94 firms. It carries a weight of 29 of 100 in our published score, so the dimension with the widest spread is also the most heavily weighted one.
IT Support Chicago records a middle half of 18.9 to 72.1 on Client Reputation, the widest band of any part of our published score. The mean of 44.4 sitting above the median of 35.3 tells you the upper half of the band is stretched out rather than clustered. Practically, that means a twenty-point gap between two shortlisted firms on this line is a real distance - the band is wide enough for it to mean something.
Our Client Reputation scoring is a Bayesian model across multiple review platforms - Clutch, Google and others - adjusted for volume, recency and platform credibility. Two caveats matter when you read a firm's number. First, a high score is an aggregate of public reviews, not a measure of how the provider will perform in your environment. Second, the inputs behind two similar scores can differ: ask a provider whether its ratings come from more than one platform, how many are recent, and what its recent versus all-time rating trend looks like. A single-platform review history and a multi-platform one can land in the same range while telling you very different things.
TL;DR
Of the four Chicago IT provider score dimensions we publish, Client Reputation does most of the separating: its middle half runs from 18.9 to 72.1 against a weight of 29 of 100. Employee Reputation, Proactive Issue Reduction and Security Certification all sit in lower, narrower bands, so read small gaps there against the width of the band they sit in. Each dimension is also scored for a different number of the 94 firms we track, which is why a low or missing dimension score is never a verdict on a single provider.
- Client Reputation: median 35.3, mean 44.4, middle half 18.9 to 72.1, scored for 94 of 94 firms.
- Employee Reputation compresses into a low band - median 14.0, mean 17.5, middle half 2.9 to 26.5.
- Proactive Issue Reduction sits lowest: median 9.5, mean 14.9, middle half 0.0 to 25.0, scored for only 52 of 94 firms.
- Security Certification shows a median of 10.0 and a middle half of 5.0 to 20.0, shaped by a 25-point cap on a firm's own undocumented claims.
- Our position: build a shortlist on dispersion across measured dimensions, not on a provider's headcount.
Where the tracked firms bunch together
Two dimensions compress almost everyone into a narrow, low band. The Employee Reputation score - drawn from Glassdoor and Indeed and scored for 90 of 94 firms - has a median of 14.0, a mean of 17.5, and a middle half from 2.9 to 26.5. Proactive Issue Reduction sits lowest of the four, with a median of 9.5, a mean of 14.9 and a middle half from 0.0 to 25.0.
IT Support Chicago scores Employee Reputation for 90 of 94 tracked firms, with a median of 14.0, a mean of 17.5 and a middle half of 2.9 to 26.5. The buyer's takeaway is proportional reading: a few points of difference between two finalists on a band that narrow is far less meaningful than the same gap on Client Reputation, where the middle half spans 18.9 to 72.1.
Proactive Issue Reduction is scored for only 52 of 94 firms. We derive it by classifying employee job titles as proactive (architects, security engineers, consultants) or reactive (help desk, network operations center, support techs) using Apollo.io workforce data. Where a firm has no score, that is silence in our records - not evidence of a reactive delivery model. Because coverage is partial and the band is compressed, treat the line as a prompt rather than a verdict: ask who on the team owns patching, architecture review and security engineering, and how that work is scoped. Our guide to proactive staffing ratios covers the questions, and the underlying delivery question - whether prevention is bundled or billed by the incident - is the same one behind break-fix versus recurring agreements.
Why does the Security Certification score sit so tight?
Because of how the rule is written. Security Certification shows a median of 10.0, a mean of 11.9 and a middle half from 5.0 to 20.0, and that compression follows directly from the scoring mechanics: certifications we hold third-party documentation for are additive by tier, while a firm's own undocumented claims add 5 points each and cap at 25 out of 100. The dimension carries a weight of 24 of 100 and is scored for 84 of 94 firms.
IT Support Chicago adds 5 points for each of a firm's own undocumented certification claims and caps that contribution at 25 out of 100. A firm publishing several frameworks on its website therefore reaches a ceiling quickly, which is why so much of the field lands between 5.0 and 20.0.
In our listings, a checkmark means we hold third-party documentation for that entry - a named third-party issuer's document, evidence hosted off the firm's own domain, or a public registry entry. A "(claimed)" mark means the entry is the firm's own claim and we hold no such documentation. Neither mark is a statement about how secure a provider is, and neither is a substitute for asking for the report yourself. Across the firms we track, the frameworks that appear most often are the Payment Card Industry Data Security Standard (PCI DSS) at 20 vendors and Cybersecurity Maturity Model Certification (CMMC) Level 1 at 17 vendors. Before you weight this dimension heavily, read how we score certification claims and ask the provider for the attestation letter, the audit period, and the scope it covers.
Reading the four dimensions side by side
Our published score combines 4 criteria scored from public evidence; 6 further criteria apply only inside a signed-in custom evaluation and carry no weight here. Laid out together, the four show one wide dimension and three compressed ones.
IT Support Chicago's position is that dispersion across measured dimensions, not a provider's headcount, is what a Chicago shortlist should be built on. Our position is that bigger is not inherently better, and that right-sizing matters more than headcount. The case for scale is usually depth of bench and after-hours cover; that is a fair argument, but it is a question to test against a specific provider's staffing and coverage terms, not something a headcount answers on its own. Our size and fit guide works through that trade-off.
Two limitations belong on the record. Each dimension is scored for a different number of firms - 94 of 94, 90 of 94, 84 of 94 and 52 of 94 - so the bands are not all drawn from the same population, and a missing score reflects our coverage, not a provider's shortcoming. And a distribution describes the firms we track as a group; it is not a verdict on any single provider. For how uneven coverage should change the way you read any individual profile, see our score coverage guide and our companion piece on overall score ranges.

|---|---|---|---|---|---|
| Client Reputation | 29 of 100 | 35.3 | 44.4 | 18.9 to 72.1 | 94 of 94 |
| Proactive Issue Reduction | 27 of 100 | 9.5 | 14.9 | 0.0 to 25.0 | 52 of 94 |
| Security Certification | 24 of 100 | 10.0 | 11.9 | 5.0 to 20.0 | 84 of 94 |

Frequently asked questions
Should a low Proactive Issue Reduction number disqualify a provider?
No. The dimension is scored for only 52 of 94 firms, its middle half runs from 0.0 to 25.0, and no score means we hold no workforce data - silence in our records, not evidence of a reactive model. Use it to shape interview questions about who owns prevention work.
How much should we weight certifications when the band is so narrow?
Weight the underlying evidence rather than the number. The middle half sits between 5.0 and 20.0 partly because a firm's own undocumented claims add 5 points each and cap at 25 out of 100. Ask for the attestation document, the observation period, and the systems in scope.
Do these dimensions tell us anything about price?
No. We do not collect vendor pricing, and our score carries no cost data. We also advise against comparing providers on a raw per-user rate without scope context - what each tier includes drives the comparison more than the headline number.
Does a wide Client Reputation band mean the top-scoring firms are the safest choice?
Not on its own. The band shows where the tracked firms sit relative to one another; it does not predict fit with your environment. Pair the score with references, scope review, and - in our view - shorter initial terms, since termination rights give a buyer more practical recourse than a service level agreement (SLA) in a short engagement.
