ThreatAware

ThreatAware is an agentless cyber hygiene platform that helps CISOs, CIOs, and SecOps leaders at mid-market and enterprises with 1,000+ devices to uniquely identify every network device and validate that key security controls are deployed, functioning and correctly configured. The platform addresses the visibility gap caused by a fragmented corporate perimeter, remote work models, and bring-your-own-device (BYOD) access. While typical enterprise cyber hygiene hovers between 70% and 80% due to untracked asset growth and control deterioration, ThreatAware closes this gap. Instead of relying on network-layer scanning or fragile metadata matching which can misidentify devices, ThreatAware uses patented Timeline Matching. This approach aligns behavioural timelines from multiple sources to deliver a 99%+ trusted asset hygiene posture with empirical proof. ThreatAware provides an automated solution for asset validation, helping teams find unknown devices on corporate networks, reconcile CrowdStrike and Intune data, or move away from manual spreadsheet reconciliation. It offers a modern alternative to legacy CAASM solutions and security control validation tools by tracking endpoint vitals on a continuous 60-minute loop to expose silent agent failures and configuration policy drift without deploying additional software agents. This automated single source of truth allows organizations to meet the strict continuous compliance demands of modern frameworks like DORA, NIS 2, and Cyber Essentials Plus. CORE PRODUCT CAPABILITIES - Identity-Layer Stealth Detection: Uncovers hidden endpoint blind spots, unprovisioned assets, and personal BYOD devices by reading authentication logs directly at the single sign-on (SSO) and identity provider level. - Independent Cross-Stack Validation: Normalises separate telemetry streams from directories, MDMs, and EDRs to confirm whether mandated security tools are actually deployed and active. - Continuous Vitals Monitoring: Tracks asset health on a continuous 60-minute loop to instantly flag silent agent failures, local policy drift, and broken communication heartbeats. - Patented Timeline Matching: Replaces brittle metadata registries by aligning multi-source behavioural timelines to uniquely identify every device. - Audit Readiness: Automates evidence collection to trace every performance metric directly back to source tool data, providing unbroken provenance for regulatory audits. USE CASES & SOLVED PROBLEMS - Exposing the "Intune Illusion": Security teams often treat MDM platforms as an absolute source of truth, ignoring that these agents are vulnerable to misconfigurations, silent crashes or BYOD bypasses. ThreatAware cross-references MDM registries against cloud application authentication streams and core directories to expose active control coverage gaps without relying on siloed vendor dashboards. - Eliminating Manual Spreadsheet Reconciliation: Manually extracting and cross-referencing device registries across tool consoles consumes up to 80 hours per cycle, creating static asset data that is obsolete immediately upon completion. ThreatAware automates the entire asset discovery lifecycle to maintain a live single source of truth, condensing audit and compliance preparation timelines from weeks to days. - Stopping Silent Agent Failures: Centralized dashboards frequently show misleading compliance metrics based on historical logs. This masks crashed agents, broken management heartbeats or localized policy drift. ThreatAware prevents these tracking deficits through continuous loop validation that directly queries the live operational status of endpoint controls every 60 minutes. TECHNICAL SPECIFICATIONS & PROFILE ATTRIBUTES Software Category: Cyber Asset Attack Surface Management (CAASM) and Cyber Asset Management platforms Deployment Framework: Built entirely as an Agentless Deployment Framework operating via secure, read-only APIs. Deployment Velocity: Rapid corporate deployment, enabling the platform architecture to go fully live within 1 hour. Data Ingestion Loops: Automated health logging with critical asset vitals tracked on a continuous 60-minute loop. Target Company Size: Developed for mid-market and enterprise organizations with at least 1,000+ active devices. Architecture Scalability: Proven in large-scale enterprise production environments with live deployments exceeding 250,000 devices. Supported Fabric Layers: Natively ingests data across Central Directories (Entra ID, Active Directory), CMDB registers, MDM, EDR, and SSO platforms. Evaluation Framework: Delivered through a low-friction, read-only API-driven Free Proof of Value (POV) Trial and comprehensive gap analysis.

NoPorts

Stop Connecting People to Networks. Connect Them to Services. NoPorts is a Zero Trust Service Access (ZTSA) tool designed to replace the broad "Network Access" model. Unlike VPNs or Mesh overlays that place devices on a virtual LAN, potentially exposing your entire subnet to lateral attacks, NoPorts creates a discrete, end-to-end encrypted tunnel to a single specific service on a device. Network Access vs. Service Access VPNs & Mesh Networks connect people to a network. If a device is compromised, the attacker can scan and move laterally across that network. NoPorts connects people, entities and devices to a service (e.g., localhost:22). They get no visibility into the rest of the network, the device's other ports, or the OS. If they are authorized for SSH, they get SSH and nothing else. Key Technical Features - True Invisibility - NoPorts uses an outbound-only architecture. There are no open listening ports on your firewall or device. Your infrastructure is invisible to Shodan, Nmap, and botnet scanners. - Granular Service Tunnels - Map a local port on your laptop directly to a remote service (SSH, RDP, VNC, HTTP, or MCP). The connection is peer-to-peer and service-specific. - Decentralized Identity - We don't store your keys. Authentication is handled via public-key cryptography on the device at the edge, ensuring NoPorts never sees your data or acts as a central point of failure. - Bypass Connectivity Hurdles - Works instantly behind CGNAT, Starlink, 4G/LTE, and firewalls without port forwarding or static IPs. Use Cases - Secure AI Agents & MCP Servers - Allow AI agents to access the various services they need to perform their duties by fully securing APIs and MCP servers, without having any of your endpoints be discoverable by unauthorized people or agents. - Starlink & Satellite Remote Access: overcome the limitations of Starlink's CGNAT (Carrier-Grade NAT) without needing to purchase a static IP or configure complex router settings. Perfect for maintaining reliable, secure connections to remote field sites, maritime vessels, and rural deployments where traditional VPNs fail. - Home Labs & Personal Servers - Securely access personal infrastructure (Home Assistant, NAS, Raspberry Pi) from anywhere without opening ports on your home router or configuring Dynamic DNS. Perfect for users behind CGNAT who need to reach specific services without exposing their entire home network. - IoT & Headless Devices - Manage remote edge devices (Raspberry Pi, industrial controllers) as if they were on your desk, even if they are buried deep behind a cellular NAT. - Sysadmin & Developer Access - Give contractors or developers access to a single server port without granting them VPN access to the corporate LAN.

AttackerView

AttackerView shows you what's broken, what's fine, and what to fix first. Type in a domain and get a full security report in about a minute. Every finding comes with real evidence (the actual HTTP response, DNS record, or certificate chain that proves the issue exists), a clear explanation of business impact, and a step-by-step fix guide tailored to your stack. What makes AttackerView different from every other scanner on this page: we don't hand you a checklist of pass/fail results. We connect findings to each other and show you the attack path. A missing email authentication record on its own is informational. That same record combined with a weak content policy and no HTTPS enforcement? That's a real way someone could impersonate your company. We show you that chain, so you know which problems to fix first and which ones can wait. AttackerView's checks update automatically when new threats are discovered. We track the US government's known exploited list (CISA KEV), CVE databases, and JavaScript library advisories, so your scans catch newly disclosed issues without you lifting a finger.
