NO
Network Oriented
Looks at the public network footprint around a domain — DNS, IPs, providers, services — not just the website.
C4C · NO PASE
Network Oriented Public Attack Surface Explorer
See what your organisation exposes to the internet — domains, subdomains, IPs, providers, services, technologies and visual evidence — before attackers or auditors do.
NO PASE maps the public-facing network surface of a domain or brand, identifies exposed services and technologies, captures visual evidence where possible, and tracks changes over time.
PAS
Public Attack Surface
Everything reachable, visible or inferable from the internet that belongs to or affects your brand.
E
Explorer
Discovers, organises and explains that surface. Not a raw scanner dump — a structured view.
// WHAT DOES NO PASE MEAN?
A domain is not just a website. It has a public network footprint.
NO PASE explores that footprint from a network-oriented view and turns it into something visible, explainable and controllable. Three concepts make that possible.
NETWORK ORIENTED
It is not just about a website.
Network Oriented means NO PASE does not only look at a website. It looks at the public network footprint around a domain: DNS, subdomains, IPs, providers, exposed services, TLS/HTTP behaviour, web surfaces and infrastructure changes.
- Root domain, subdomains and DNS records
- Public IPs, ASN, hosting, cloud and CDN providers
- TLS certificates, HTTP behaviour and exposed ports
PUBLIC ATTACK SURFACE
Everything reachable, visible or inferable from outside.
The public attack surface is everything reachable, visible or inferable from the internet that belongs to or affects a domain, brand or organisation — including the parts your team did not realise were public.
- Reachable HTTP/HTTPS services, admin panels and login pages
- Mail security posture (SPF, DKIM, DMARC) and certificate state
- Third-party infrastructure visible from the public internet
EXPLORER
Structured exploration, not scanner output.
Explorer means NO PASE discovers, organises and explains the public surface. It does not just dump scanner output. It builds a structured view that executives, CISOs and analysts can use.
- Grouped by domain, subdomain, provider, country and technology
- Visual evidence next to the data that produced it
- Differential view: what changed since the previous scan
// SEVEN QUESTIONS NO PASE ANSWERS
Built around the questions a CEO, a CISO and an analyst all need answered.
01
What public network surface belongs to this domain or brand?
NO PASE maps domains, subdomains, public IPs, providers and infrastructure visible from the internet.
02
Which assets are visible from the internet?
Each discovered asset is classified by state — live, DNS-only, filtered, exposed or unresolved — so you can see real reachability.
03
Which services, technologies and providers are exposed?
NO PASE fingerprints HTTP/HTTPS services, TLS, technologies and groups them by provider, ASN, country and family.
04
What visual evidence exists?
When reachable HTTP/HTTPS surfaces are available, NO PASE captures screenshots that show what the outside world sees.
05
What has changed since the last scan?
Differential monitoring compares every new snapshot to the previous baseline and surfaces additions, removals and risky changes.
06
What matters from a risk and business perspective?
Findings are graded by severity, confidence, evidence and business impact so the priority is obvious.
07
What should be reviewed, fixed or monitored?
Each finding has a recommended next step and each surface area has a clear monitoring hint for ongoing control.
// MACHINE-READABLE SERVICE SUMMARY
Entity
Product: NO PASE — Network Oriented Public Attack Surface Explorer. Company: Check 4 Cyber (C4C). Relationship: NO PASE is the public attack surface explorer developed and operated by C4C.
Core workflow
Add a domain or brand → discover its public network surface → identify exposed services and visual evidence → review findings → monitor differential changes over time.
Primary users
CEOs who need to know what their organisation exposes, CISOs who need differential control, and analysts who need defensible evidence and remediation pointers.
Differentiation
NO PASE is network-oriented: it does not collapse into a screenshot tool, a vulnerability scanner or a subdomain enumerator. It is a structured explorer of the entire public attack surface.
// HOW IT WORKS
01
01 · Add a domain or brand
Authorise the asset you want explored. NO PASE only maps surfaces you control or have permission to assess.
02
02 · Explore the public network surface
NO PASE discovers subdomains, IPs, providers, DNS records, exposed services, TLS posture, technologies and reachable web surfaces.
03
03 · Monitor differential changes
Every new snapshot is compared against the previous one. New, removed and changed assets are surfaced with risk context, not raw counts.
// INSIDE THE NO PASE REPORT
Six structured views of your public network attack surface.
Every NO PASE report is built from the same six sections, so an executive, a security lead and an analyst can read the same document and each find what they need.
01

// SEE NO PASE IN ACTION
From a single domain to your full public network surface.
Each block below shows one slice of the NO PASE report — the same evidence-driven views you get for every domain or brand you scan.
Network-oriented exploration of what an outsider — attacker, auditor or customer — can see, infer or reach.
01
EXECUTIVE SUMMARY
One domain becomes a board-readable view of public exposure
NO PASE turns a single domain into a network-oriented summary an executive can read in 30 seconds: how many public assets exist, how many internet-facing services respond, how many findings need attention, and how many changes happened since the last scan.
- Public assets, internet-facing services, findings and changes — at a glance
- Activity since the last scan, surfaced as deltas not raw counts
- Recommended next actions, ranked by business impact
// EXECUTIVE TAKEAWAY
A CEO sees the shape of public exposure in seconds — without reading scanner output.

PUBLIC NETWORK SURFACE
Explore the network surface — providers, ASN, country, technology
Every node is a real asset NO PASE discovered. Every edge is a verified network relationship. Group by provider, ASN, country, technology or severity to see clusters of risk that a flat list would never reveal.
- Real discovered assets — clickable, filterable, exportable
- Grouped by provider, ASN, country, technology or severity
- Reveals shadow infrastructure, vendor sprawl and concentration risk
// EXECUTIVE TAKEAWAY
Your infrastructure stops being a spreadsheet and becomes a network you can interrogate.

VISUAL EVIDENCE
Visual proof of what reachable web surfaces actually expose
When NO PASE finds reachable HTTP/HTTPS surfaces, it captures screenshots of the admin panels, login pages, applications and portals that are visible from the internet. Each one is annotated with the finding, the risk and the recommended action.
- Captured admin panels, login pages and reachable applications
- Each card explains the finding, the risk and the next step
- Defensible evidence for audit, board and remediation tickets
// EXECUTIVE TAKEAWAY
When a CEO asks "what does an attacker actually see?", you can show them.

DIFFERENTIAL MONITORING
Catch new public exposure the moment it appears
A scan is a photo. NO PASE is the film. Every new snapshot is compared against the previous one — new and removed assets, DNS changes, TLS changes, provider swaps, technology drift, newly exposed services — surfaced with context, not noise.
- Detects new, removed and changed assets between snapshots
- Tracks DNS, TLS, provider, technology and service changes over time
- Built for continuous monitoring of monthly and yearly subscriptions
// EXECUTIVE TAKEAWAY
You stop discovering exposure during incidents and start discovering it during deployments.

// DIFFERENTIAL MONITORING
A scan is a photo. NO PASE is the film.
One-time scans are useful. Continuous differential monitoring is operationally critical because the public network surface keeps changing — after deployments, vendor swaps, DNS moves, certificate rotations and infrastructure drift. NO PASE highlights what changed, where it changed, and why the change matters.
Daily automated exploration
NO PASE re-explores your domains every 24 hours and compares the result against the previous snapshot.
Immutable snapshot history
Each completed exploration is stored as a durable state record so changes are explainable in retrospect.
Structured differential analysis
Compare any two snapshots across DNS, ports, services, TLS, providers, technologies and findings.
Severity-aware change prioritisation
Changes are classified by operational risk so teams can focus on what matters first.
Provider, ASN and country awareness
Differential alerts cover provider swaps and geographic moves — not just port changes.
Executive-readable reporting
Export a board-readable view alongside the technical evidence analysts need.
// FAQ
What is NO PASE in one sentence?
NO PASE is a Network Oriented Public Attack Surface Explorer: it shows what your organisation exposes to the internet from a network-oriented perspective — domains, subdomains, IPs, providers, services, technologies, screenshots, findings and changes over time.
What does Network Oriented mean?
NO PASE does not only look at a website. It looks at the public network footprint around a domain: DNS, subdomains, IPs, providers, exposed services, TLS/HTTP behaviour, web surfaces and infrastructure changes.
What is the public attack surface?
The public attack surface is everything reachable, visible or inferable from the internet that belongs to or affects a domain, brand or organisation — including infrastructure your team did not realise was public.
Why is NO PASE called an Explorer and not a scanner?
A scanner dumps raw output. NO PASE explores: it discovers, organises and explains the public surface so executives, CISOs and analysts can use the same report.
Is NO PASE a vulnerability scanner?
No. NO PASE is a public attack surface explorer. It identifies what is exposed, fingerprints services and providers, captures evidence and tracks changes — vulnerability detection is one part of the wider picture, not the whole product.
What is a snapshot in NO PASE?
A snapshot is an immutable record of the observed public surface for a domain at the moment of exploration. Snapshots become the baseline that future scans are compared against.
What is differential monitoring?
Differential monitoring compares snapshots over time to identify added, removed and changed assets, services, providers, certificates, technologies and findings — so your team detects drift before incidents do.
Who is NO PASE for?
CEOs who need to know what their organisation exposes, CISOs who need differential control over that exposure, and analysts who need defensible evidence and clear remediation pointers.
