Any EDI managed service provider can make promises by claiming to be an “industry leader” when it comes to cybersecurity. How do you actually vet out the EDI vendors you are looking into to be sure you can trust them with your businesses sensitive data? The first step is looking into unbiased, independent data from credible sources. For over three years, SecurityScorecard has consistently rated Promethean Software Services at an A rating, ranging from 91 to most recently, the current evaluation reflects a perfect score of letter grade A (100/100). The data does not lie: Compared to competitors and industry averages, SecurityScorecard’s ratings vet out Promethean to truly be the most secure EDI Managed Service Provider.
Why Trust SecurityScorecard?
SecurityScorecard is widely recognized as a leading authority in cybersecurity ratings, offering continuous assessments of more than two million organizations worldwide. Their core goal is to help create a safer digital environment by changing how companies evaluate, strengthen, and communicate their cybersecurity posture.
SecurityScorecard is widely validated by independent analyst firms and trusted by some of the biggest companies in the world. In Forrester’s 2024 Wave report, it earned the top score in 17 of 25 categories and was the only vendor publishing live transparency metrics like dispute resolution rates and response times. It also holds a FedRAMP Ready designation, serves over 70% of the Fortune 100, and continues to grow rapidly, backed by strong third-party research on cyber risk and supply chain security.
What do SecurityScorecard Scores Mean?
One of the most useful things about SecurityScorecard is how straightforward their scoring system is. Every organization receives a letter grade (from A to F) that reflects the strength of its cybersecurity posture. Behind that simple scale is a detailed, data-driven methodology designed to show how likely a company is to face a breach.
A Simple Grade With Real Predictive Power
SecurityScorecard ratings translate complex security signals into a score from 0 to 100, which is then mapped to a letter grade. An “A” means the company has a strong security posture. Lower grades indicate a much higher chance of a breach.
Under the current “Scoring 3.0” model, companies with an F (≤60) are 13.8× more likely to experience a breach than companies with an A (90–100). This is derived from real breach data analyzed across tens of thousands of incidents.
This letter grade system is a powerful reminder of how important it is to research managed service providers security standings as they can predict either security safety or a high risk of breach. The scores also help gain insight as to what vendors actually care about your business just as much as you do.
Why These Scores Matter
Because the scoring model connects directly to real breach outcomes, the ratings serve as a reliable predictor of risk. For example:
-
B rated companies are about 2.9× more likely to be breached than an A-rated one.
-
C rated companies are roughly 5.4× more likely to experience a breach.
-
D ratings jump to 9.2×.
-
And an F hits the 13.8× risk level previously mentioned.
For security teams, this makes the score an actionable metric. The rating reflects how committed a company is to their security efforts as SecurityScorecard ratings are updated continuously. It is insightful to see which vendors fix issues and which neglect their security standings.
It’s also critical to remember that when your company connects to an EDI provider (or any third-party vendor) you immediately inherit that vendor’s security risk. No matter how strong your internal defenses are, the moment you exchange data with a partner that has weak security, your exposure rises to match theirs. Every year, countless organizations experience breaches not always because of their own vulnerabilities, but because they were connected to an insecure third‐party system. This is why monitoring vendor ratings is so important: an “A” rated internal environment can still be compromised if it relies on a “C,” “D,” or “F” rated partner. Understanding this shared-risk model helps security teams prioritize which relationships may require additional scrutiny, safeguards, or even vendor replacement.
