BitSight vs SecurityScorecard: own-organization performance and vendor monitoring are different purchases

Own-organization security performance and vendor-portfolio monitoring are two subscriptions. BitSight for Security Performance Management on AWS Marketplace is USD $138,550.00 per license per 12 months for the SPM Enterprise Combined dimension, including 20 benchmarking subscriptions. That line is not Continuous Monitoring, which is the third-party product and did not publish a dollar rate on its product page. SecurityScorecard gives a free Scorecard for your own domain. Paid TITAN is priced by how many organizations you monitor, and the pricing page does not publish those dollars.

After the purchase is named, the operating questions are the same on both sides: which assets were attributed to the company, how that company disputes a finding, how much of the math you can see, how the two companies work the finding together, and how fresh the observation is. A 300-820 BitSight rating or an A-F Scorecard (mapped to 100 through 0) is outside-in evidence. It is not a penetration test and it does not prove the absence of a breach. Broader shortlists sit under vendor risk tools. An adjacent ratings compare is SecurityScorecard vs UpGuard.

	BitSight	SecurityScorecard
Two purchases	Security Performance Management for your own organization. Continuous Monitoring, with optional Vendor Risk Management, for the vendor portfolio. Do not put both on one invoice line.	Free Forever Scorecard for your own domain. Paid TITAN Watch, Assess, or Secure for organizations you monitor and manage. The pricing page says usage is that organization count.
Rating you see	Security Ratings page: 300-820, with a letter grade per risk vector. The January 2026 methodology PDF says the normalized scale is 250-900 and the effective range at publication is 300-820 because the edges are reserved.	A through F, mapped to a numeric score from 100 through 0. The help center (updated 1 June 2026) says an A is 90 to 100 and an F is 60 or lower.
Day-to-day work	On SPM, benchmark your organization and track remediation of externally observed findings. On Continuous Monitoring, alert on vendor rating changes, fourth parties, and vendor communication.	On the free Scorecard, manage your digital footprint and your own findings. On paid TITAN, vendor directory, intake, tiering, and a communication center. Questionnaires are on Assess. Threat-informed findings and fourth-party detection are on Secure.
Who operates it	Security performance owners for SPM. Third-party risk owners for Continuous Monitoring. Those can be the same people, but they are not the same subscription.	The team that owns the company Scorecard, and the third-party risk team that staffs Watch, Assess, or Secure.

Pages opened 3 Oct 2026: BitSight Security Ratings, the January 2026 methodology PDF, Continuous Monitoring, and the AWS Marketplace SPM listing; SecurityScorecard pricing, the score-calculation help center, the digital-footprint help article, and the findings-resolution blog. This is not a paid-tenant test.

BitSight

SecurityScorecard

Own organization and vendor monitoring

Match currency, unit, period, commitment, and the product named on the line. A Security Performance Management license does not buy a vendor portfolio, and a free own-domain Scorecard does not buy TITAN monitoring.

	BitSight	SecurityScorecard
Own organization	Bitsight for Security Performance Management. Marketplace dimension SPM Enterprise Combined: USD $138,550.00 per license per 12 months, includes 20 benchmarking subscriptions. Annual subscription. The listing says access follows the subscription start, later orders are provided within two business days, and the term renews for another 12 months unless cancelled with 30 days’ written notice. No refunds on that listing.	Free Forever Scorecard for your own domain, USD $0. The pricing FAQ says there is no limit on how many users can access that free Scorecard. Included work on the pricing page includes the rating, digital footprint, open issues, remediation priority, score-change alerts, questionnaire response, and summary reports.
Vendor monitoring	Continuous Monitoring, sold as SaaS for third-party posture, fourth-party and nth-party visibility, and vendor collaboration. A public dollar amount was not on the Continuous Monitoring page opened 3 Oct 2026. Ask the quote for vendor count, term, and whether Vendor Risk Management is a separate line.	TITAN Watch, Assess, and Secure, plus TITAN OS on the comparison table. The pricing page says the price factor is the number of organizations you monitor and manage. No dollar amount is published there. Marketplace resale is offered. A current public Marketplace dollar amount for paid TITAN was not found in the pages opened.
Do not mix the lines	The $138,550.00 figure is SPM Enterprise Combined only. It is not a Continuous Monitoring portfolio total.	The free Scorecard is self-monitoring. It is not a price per monitored vendor.

Attribution, disputes, transparency, collaboration, freshness

These are the checks that decide whether a red finding should hold an onboarding. Read the same row on both vendors before treating one path as missing.

	BitSight	SecurityScorecard
Attribution	Ratings page: findings are mapped with company relationships, asset mapping, IP and CIDR blocks, DNS, and subsidiary attribution. The governance copy describes AI plus researchers maintaining entity links. A published sample accuracy percentage, comparable to the SecurityScorecard audit below, was not found in the BitSight pages opened.	Help center: signals are tied to IPs or domains, then to the digital footprint. Detection methods in the footprint article include DNS lookups, port scans, published cloud and provider ranges, SSL certificate sightings, user-contributed data, repeated platform logins from the same IP, third-party feeds, and regional internet registries. Their findings-resolution blog reports a commissioned check: 94 percent IP accuracy on 1,480 addresses across 13 companies, and 100 percent domain accuracy on 377 DNS records across 13 companies. That is their published sample, not a measurement from this page.
How a company disputes a finding	The January 2026 methodology PDF says every rated organization, not only customers, can challenge assets, findings, and the interpretation of findings. The Policy Review Board governs the algorithm and adjudicates appeals. For scan-visible fixes on supported vectors, the ratings FAQ says you do not submit proof: remediate, request a rescan, and the next daily rating picks it up.	The findings-resolution blog says non-invasive monitoring only sees public-facing controls, so a company can refute a finding with evidence when an internal compensating control is invisible. Their refute materials say customers and non-customers can challenge IPs, domains, and findings. Support review is described as within 48 hours. If approved, a projected score can show within minutes, and the blog says the Scorecard update follows documentation review in 48 to 72 hours. A denial comes back with an explanation.
How transparent the rating is	Letter grades per risk vector, a public ratings method page, a knowledge base for calculations, and the Principles for Fair and Accurate Security Ratings. The methodology PDF describes normalization onto 250-900 with an effective 300-820 band. Weight of a single finding inside a drop was not spelled out as a customer-facing formula on the pages opened.	Issues tab with High, Medium, and Low severity, ten factors (Network Security, DNS Health, Patching Cadence, Endpoint Security, IP Reputation, Application Security, Cubit Score, Hacker Chatter, Information Leak, Social Engineering), and a modified z-score that compares finding counts with organizations of similar footprint size. Informational and positive issues do not change the score. The help center points to a scoring methodology whitepaper.
Collaboration	Continuous Monitoring’s vendor-collaboration section says teams use the external evidence to drive remediation and centralize vendor communication in one place. That is a paid monitoring workflow, separate from the Policy Review Board path any rated organization can use.	Free Scorecard holders remediate and refute their own domain. On paid TITAN, the pricing comparison marks a communication center, contact manager, vendor directory, intake, and tiering as included on Watch, Assess, and Secure. Assess adds questionnaire templates and review. Secure adds response automation and remediation tracking. A free vendor-portfolio communication center was not described on the pricing page.
How fresh the data is	Ratings are recalculated daily. Dynamic Remediation, powered by Groma, is live on five risk vectors: SSL Configurations, SSL Certificates, Open Ports (TCP), Server Software, and Web Application Security. Rescan results can appear within minutes. The rating change is the next daily update.	Factor and total scores update daily. A full IPv4 scan, more than 3.9 billion routable addresses and more than 1,400 ports, is every 10 days. Cloud assets are scanned multiple times daily. Calibration uses two months of data, and the algorithm is recalibrated every quarter. An approved refute is not the same clock as the 10-day scan.

That comment is the edge case after the clocks above, not the reason to pick a vendor. BitSight’s documented answer on the five Groma vectors is an on-demand rescan and the next daily rating, without an evidence packet. SecurityScorecard’s documented answer for a contested finding is the refute review, then 48 to 72 hours for the Scorecard after approval. A fix outside those five BitSight vectors, or a SecurityScorecard issue that is not yet approved, can still sit. A matching minute-level rescan promise for every SecurityScorecard issue type was not found in the pages opened, and a matching 48-hour dispute SLA for every BitSight Policy Review Board appeal was not found either.

What a rating does not prove

Both products score externally observed signals. BitSight groups them as compromised systems, organizational diligence, user behavior, and public disclosures. SecurityScorecard’s blog says the platform can verify public-facing controls and can miss an internal compensating control until someone refutes the finding. Use the number for that job only.

• It does not prove the design or operation of controls that never touch the public internet, including internal Active Directory, endpoint controls, or segmentation. A Marketplace reviewer of BitSight made that limit explicit, and SecurityScorecard states the same outside-in limit.
• It does not prove a questionnaire. Continuous Monitoring can sit beside assessments, and SecurityScorecard Assess runs questionnaires, but the grade itself is not the evidence in the PDF.
• It does not prove a company will or will not be breached. BitSight cites outside studies that correlate ratings with incidents. SecurityScorecard publishes that an F is 13.8 times more likely to sustain a breach than an A. Correlation is not a prediction of the next incident, and a drop is not by itself proof that a breach already happened.
• It does not prove the asset is theirs until attribution is checked. Parent and subsidiary mix-ups and third-party infrastructure show up in BitSight reviews. SecurityScorecard’s own sample audit is 94 percent of 1,480 IPs, which still leaves misses, and the footprint can be claimed or refuted.

Choose BitSight Security Performance Management when the subscription is your organization’s 300-820 performance, peer benchmarks, and remediation tracking, and price that as the Marketplace SPM Enterprise Combined license rather than as vendor monitoring. Choose BitSight Continuous Monitoring when the subscription is the vendor portfolio and you will confirm the dollar amount, vendor count, and term on the quote. Choose SecurityScorecard’s free Scorecard when the work is your own domain at USD $0. Choose paid TITAN when the work is organizations monitored, and match Watch, Assess, or Secure to communication, questionnaires, or threat-informed response on the order form.
