NexTraceBot — The crawler behind NexTrace Search
NexTrace is building a specialized search engine for cybersecurity research, advisories, vulnerabilities, and threat intelligence. We crawl publicly accessible security content so researchers can discover it — and when they find your content through NexTrace, they are sent directly to your website.
How NexTrace Drives Qualified Discovery
A transparent referral model connecting original research with active security practitioners.
Your Research
You publish security research, threat advisories, malware analysis, or vulnerability reports.
NexTrace Indexing
NexTraceBot indexes and semantically categorizes your publicly accessible technical findings.
Researcher Search
Security teams search NexTrace for specific CVEs, threat actors, IOCs, or TTP techniques.
Referral Visit
Researchers click through directly to your website to read your full analysis and original findings.
Why Publishers Allow NexTraceBot
We design our crawler to maximize your visibility while respecting your infrastructure.
More Qualified Discovery Traffic
Your original research becomes discoverable to security professionals actively searching for specific threats, vulnerabilities, threat actors, malware samples, and defense techniques.
More Discovery for Older Content
High-value threat research and technical vulnerability writeups often retain long-term relevance. NexTrace ensures older, in-depth research continues receiving targeted discovery traffic.
Direct Attribution to Your Site
NexTrace links search results directly back to the original source rather than attempting to summarize away or replace the source article.
Polite & Efficient Crawling
Low concurrency, intelligent rate limiting, aggressive caching, and exponential backoff on HTTP 429/503 are engineered to minimize any impact on your origin servers.
You Stay in Full Control
You can restrict crawl rates, specify excluded directories, or block NexTraceBot entirely at any time through standard robots.txt instructions.
Direct Publisher Support
Have questions, bandwidth considerations, or want to expedite indexing of a critical zero-day disclosure? Our crawler team is directly reachable for webmaster requests.
What NexTrace Indexes
NexTraceBot is strictly purpose-built for public security and threat intelligence research.
- Public cybersecurity research papers, blogs, and advisories
- CVE analyses, exploit breakdowns, and remediation notes
- Threat actor profiles, TTP mappings, and malware technical reports
- Open-source detection rules (YARA, Sigma, Snort) and documentation
- No bypassing of paywalls, authentication, or login portals
- No vulnerability scanning, fuzzing, port scanning, or active probing
- No collection of private user data or sensitive customer information
- No high-frequency bursting that stresses publisher infrastructure
