NYLE
StackScan helps businesses find and analyze websites based on the technologies they use or the keywords they target. Instead of manually researching websites one by one, users can instantly search across 100M+ domains and identify sites using platforms like Shopify, WordPress, WooCommerce, Webflow, and thousands of other technologies.
The platform provides practical filtering tools that allow users to narrow results by country, TLD, industry, or specific technology combinations. This makes it useful for building targeted lead lists, researching competitors, discovering niche markets, or identifying companies using certain software stacks for outreach and partnerships.
StackScan also supports bulk data downloads, keyword-based website discovery, and structured reporting to simplify large-scale research workflows. With continuously refreshed datasets and scalable search capabilities, it enables marketers, agencies, analysts, and growth teams to access actionable web intelligence quickly and efficiently.
NYLE is a FedRAMP High gap analysis tool purpose-built for product and security teams pursuing federal authorization. Instead of spending $100Kโ$200K and 6โ10 weeks on a traditional consulting engagement to assess your posture against FedRAMP High, NYLE delivers a complete gap analysis in 7 daysโwith FedRAMP Moderate and Low coverage included at no additional cost.
NYLE's guided assessment is analyzed against the full set of NIST 800-53 Rev. 5 controls and completed by your team directly in the portal or via CSV for parallel routing across Security, IAM, Engineering, IT, HR, Legal, and other functional owners. No prerequisites, no integrations, no external consultantsโyour license activates and work begins the same day.
Every license includes a live readiness dashboard with control-level drilldown, a board-ready assessment report you can present directly to leadership or agency sponsors, control status exports for your GRC tooling, and control-by-control remediation guidance so engineering can close gaps without follow-on consulting. You also get a Gap Analysis Playbook for running the assessment internally, an Agency Positioning Guide for sponsor conversations grounded in real data, and a Cross-Functional Workbook for keeping every function aligned.
Unlike traditional consulting, which delivers a point-in-time static report, NYLE gives you 12 months of unlimited access to update your responses, refine evidence, and watch your readiness posture evolve as you remediate. Your assessment outputs feed directly into SSP development and reduce the scope, cost, and duration of your eventual 3PAO engagement.
NYLE is not a 3PAO, a pen test, or a commercial compliance platform like Vanta or Drata. It's purpose-built for the first (and most critical) stage of FedRAMP High authorization: knowing exactly where you stand, what to fix, and how to get to ATO faster.

StackScan's answer
StackScan focuses on practical usability, broader stack coverage, advanced filtering, and scalable exports without unnecessary complexity. Users can quickly generate highly targeted datasets using filters like country, TLD, industry, and technology combinations, making research and lead generation faster and more precise.
NYLE's answer:
Three reasons: cost, speed, and scope. NYLE delivers a complete FedRAMP High gap analysis in as little as 7 days, compared to 6-10 weeks with a traditional consulting firm, and includes FedRAMP Moderate and Low baseline coverage at no additional cost. Unlike consultants, NYLE gives you a living assessment your team controls, with built-in control-by-control remediation guidance and an agency sponsorship playbook to move you toward ATO faster. No sourcing, no vetting, no contracting - start the day your license activates.
StackScan's answer
StackScan combines technology stack discovery and keyword-intent research in a single platform, allowing users to find websites not only by the tools they use but also by what they are targeting online. With coverage across 50,000+ technologies and 100M+ domains, it provides scalable, filterable, and export-ready web intelligence.
NYLE's answer:
NYLE is the only FedRAMP gap analysis tool purpose-built to replace the traditional consulting engagement. Where consultants deliver a $150K+ point-in-time static report after 6-10 weeks, NYLE gives your team a guided assessment mapped to NIST 800-53 Rev. 5 that's complete in as little as 7 days, with 12 months of live access to update your posture as your system changes. It's a living readiness picture, not a one-time deliverable.
StackScan's answer
StackScan is built for marketers, growth teams, agencies, sales teams, analysts, SaaS companies, and researchers who need structured web intelligence for prospecting, competitor analysis, market research, or technology adoption tracking.
NYLE's answer:
NYLE is built for product, security, and GRC leaders at SaaS and cloud companies pursuing FedRAMP High authorization, particularly those exploring federal market expansion who need to scope the effort before committing to a full consulting engagement. Typical buyers include CISOs, GRC teams, U.S. Federal/Public Sector teams at commercial companies, and founders evaluating the cost and timeline of pursuing public sector customers. NYLE serves teams at any readiness level, from companies just exploring FedRAMP viability to those preparing for imminent 3PAO assessment.
StackScan's answer
StackScan was created to simplify the process of finding reliable website and technology data at scale. Existing solutions often felt limited, expensive, or difficult to use for targeted workflows, so StackScan was built as a practical and scalable platform that combines technology detection, keyword discovery, and bulk data access into one system.
NYLE's answer:
NYLE was built by practitioners who've sat on every side of the FedRAMP table: inside federal agencies authorizing cloud services at the CIA, NIH, DoD, and the Defense Innovation Unit; inside the hyper-scaler delivering compliance at scale on Google Cloud; and inside the enterprise earning the authorization, leading the first FedRAMP ATO for a frontier AI lab at Anthropic. The founding team watched companies spend six figures and months on consulting engagements just to learn where they stood, then spend on average $1M to update that picture as they worked towards ATO. NYLE is what they wished they'd had: a faster, cheaper, continuously updatable path to FedRAMP readiness, so teams can save their consulting budget for the stages where it truly matters.
StackScan's answer
StackScan is built using modern web technologies, large-scale crawling systems, distributed data processing, and technology fingerprinting engines designed to analyze and structure massive amounts of web data efficiently.
NYLE's answer:
NYLE is a SaaS product built on Bubble.io and Replit (PaaS), with infrastructure hosted across Google Cloud and AWS (IaaS). We're CIS Level 1 compliant and are happy to share our architecture, technology stack and security posture with prospective customers under NDA.
StackScan's answer
StackScan is used by agencies, SaaS businesses, growth teams, researchers, and data-driven organizations for lead generation, market intelligence, and competitive analysis across multiple industries.
NYLE's answer:
NYLE works with SaaS and cloud companies across the federal market, ranging from early-stage startups exploring FedRAMP viability to established platforms preparing for 3PAO assessment. Customer names are kept confidential at this stage until our customers publicly announce their successful ATO.
While itโs still in early stage, its lifetime deal is really a great value. Must get if youโre into lead generation.
