Concrete inventory of the surface
CSURFACE discovers exposed assets from the root domain — including shadow IT, subsidiaries, and digital supply chain. The result is a concrete attack surface relationship, not an aggregated signal synthesis.
BITSIGHT · TWO DIFFERENT JOBS
Posture scoring and proof of exposure solve different problems.
Bitsight does what it sets out to do: produce a comparable measure of a company's apparent posture, useful for tracking a vendor portfolio over time. This page does not contest that measure. It shows where it stops, and what you need to know after it.
WHEN EACH ONE SERVES
The comparable measure and the specific evidence
Tracking hundreds of vendors calls for a standardized measure, one that moves over time and that a committee understands without translation. That is what posture scoring exists for, and it is a legitimate portfolio-management problem.
The question the score does not answer is about the asset. It does not say whether that specific host, in the configuration it is in today, can be exploited from the internet. That is no product limitation: it is what an aggregate measure does not set out to do.
CSURFACE answers that second question and hands over the evidence with it. The finding ships with the proof the target itself returned and an explicit confidence grade, so that the decision to treat or not treat rests on facts.
In practice the two add up: the score organizes the portfolio, and the proof decides what enters this week's remediation queue.
CAPACITY COMPARISON
BitSight and CSURFACE, Side by Side
The comparison is on capacity and aims to be honest — including where the security rating has a clear advantage.

This table compares distinct product categories. BitSight is a posture security rating; CSURFACE is a platform for continuous discovery, prioritization, and validation. Both approaches can coexist in the same security program.
WHERE CSURFACE DIFFERS
From posture scoring to exposure reduction work
Confirmation of what is exploitable
A posture rating points to apparent vulnerabilities. CSURFACE confirms whether the exposure is actually exploitable, eliminating noise before it enters the team's work queue.
Threat-driven prioritization
Remediation order follows threat intelligence and evidence of active exploitation, cross-referenced with the criticality of each discovered asset — not a static posture snapshot.
Business context for each asset
Machine Learning classification assigns criticality to each asset. The team understands what is exposed and, with equal precision, how much each exposure matters to operations.
A vision that does not age
The external surface is continuously re-evaluated, with alerts on new assets and relevant changes. The information reflects the current state, not a previous assessment.
Findings ready for action
Each finding reaches the responsible team with context and remediation suggestion. The deliverable is actionable remediation work ready for execution.
FREQUENTLY ASKED QUESTIONS
FAQ
Does CSURFACE replace BitSight?
It depends on the objective. If the need is a recognized security rating to evaluate large supplier portfolios, then the security rating fulfills that role with maturity. If the need is to discover your own external attack surface, classify assets by criticality, and validate what is exploitable, this requires a discovery and validation platform. Both approaches serve different purposes and can coexist.
Is BitSight's market recognition a real advantage?
Yes, and we recognize this directly. In contexts where the rating needs to be understood and accepted by multiple parties—including third parties and insurers—the familiarity of the market with the BitSight format carries weight. CSURFACE belongs to another product category and does not compete for that space; it complements the posture view with discovery and validation.
Does CSURFACE produce a score?
The platform generates an exposure index that summarizes the state of the external surface. The purpose is different from a market posture rating: the index guides discovery, prioritization, and validation work instead of serving as a standalone metric for company comparison.
Does CSURFACE require agents or internal network access?
No. Discovery is entirely external and starts from the organization's root domain. There are no agents to install, nor a need for internal network credentials.
The platform operates autonomously. Optionally, CSURFACE integrates with cloud environments, WAF, CIEM, and other sources to enrich analysis—integrations that expand the context but are not necessary for the platform to function.
