Cybersecurity and Threat Hunting
Tuxxin monitors what your business exposes to the internet, hunts for threats aimed at it, locks down email authentication and plans incident response.
Cybersecurity is one of the four pillars of the Tuxxin Annual IT Program, and most clients begin with the fixed-price IT cost and security assessment, from $2,500.
Cyber Insurance Readiness
Cyber insurers ask for specific security controls on applications and renewals. The assessment checks each control below and records which ones are in place. Tuxxin implements the missing controls on the systems it maintains and works with your office staff or desktop provider to close endpoint gaps.
- Multi-factor authentication (MFA)
- Endpoint protection
- Tested backups
- A written incident response plan
What the Cybersecurity Service Covers
Exposure Monitoring
Recurring external scans of your public footprint, using the engine behind qsa.sh, surface open ports, stale services, exposed admin panels and misconfigurations.
Threat Hunting
Hunts for traffic-distribution systems (TDS), malware droppers and command-and-control callbacks, guided by live honeypot telemetry.
Email Authentication
SPF, DKIM and DMARC for every domain you send from, so receiving mail servers can reject messages that forge your domain.
IP and URL Intelligence
worldip.io adds proxy detection, ASN and hosting context, and PTR and DNS history to any address. whack.sh scans suspect URLs from several network vantage points to expose cloaking.
Look-Alike Domain Monitoring
issued.live watches Certificate Transparency logs and new domain registrations for look-alike domains and unauthorized certificates aimed at your brand.
Incident Response
When something gets through, Tuxxin helps triage, contain and clean up, then files abuse reports with threat-intelligence feeds and hosting providers to take the attacker infrastructure down.
Threat Data From Our Own Sensors
- Tuxxin collects threat data first-hand on honeypots and scanners it operates.
- Our whack.sh scanner reports confirmed threats to URLhaus, MalwareBazaar and AlienVault OTX.
- Our own products run on a network replicated across multiple continents.
Check Your Own Domain
qsa.sh
An instant external security scan of the public IP address you connect from. Run it from your office network.
Run a scan on qsa.shworldip.io
Look up your domain or any IP address: ownership, ASN, geolocation and reverse DNS.
Look up a domain or IP on worldip.ioOur Threat-Intelligence Tools
Honeypots and Sensors
A distributed network of honeypots captures attacker and scanner activity in real time: credential stuffing, exploit attempts and new scan patterns, which feed fresh indicators of compromise into each hunt.
worldip.io
Our IP-intelligence platform: proxy and VPN detection, hosting and ASN context, PTR history and a DNS timeline for any address or domain.
whack.sh
A multi-egress URL threat scanner. It loads a suspect link through datacenter, residential and mobile networks at the same time and compares the responses to expose cloaking and traffic-distribution systems.
qsa.sh
An instant, anonymous external security scan with nothing to install. Results live only in memory and expire after 24 hours or a single read.
curlhub.sh
A privacy-first HTTP inspection tool. Like qsa.sh it is fully anonymous: stored data lives only in memory and expires after 24 hours or a single read.
issued.live
A real-time feed of Certificate Transparency logs and new domain registrations, so a look-alike domain and its certificate surface as they are issued.
Coming Soon: infil.io and cde.red
infil.io, a live ingestion feed from a rotating fleet of honeypots, and cde.red, single-use monitoring that raises an alert when a check-in is missed.
Our Delivery Process
-
Assess
The fixed-price assessment maps your internet-facing systems and brand domains, runs an external scan with manual validation and reviews SPF, DKIM and DMARC. You get a prioritized 90-day plan.
-
Monitor and Hunt
Continuous exposure monitoring plus scheduled threat hunts informed by honeypot telemetry. New look-alike domains, exposures and malicious URLs are flagged as they appear.
-
Respond
Each finding comes with a prioritized report: what it is and what to do. For an active incident, Tuxxin helps contain and remediate directly.
-
Report and Take Down
Confirmed malicious infrastructure goes to the right abuse channels and threat-intelligence feeds.
Cybersecurity and Threat Hunting Is Right for You If
- Your cyber insurance application or renewal asks about MFA, endpoint protection, backups or an incident response plan.
- You have a public-facing brand, storefront or customer portal and worry about phishing, look-alike domains or account-takeover fraud.
- Bots and scanners hammer your sites, and you need to tell real customers from automated abuse.
- You want threat hunting and incident response without staffing a security team in-house.
- You had a security incident or a near miss and want help with response, cleanup and takedowns.
