SOLUTIONS / THREAT INTELLIGENCE AND SOC ANALYSTS
Agentic OSINT for Threat Intelligence and SOC Analysts
Nexus is an agentic OSINT platform that threat intelligence and SOC analysts use to enrich indicators and investigate attacker infrastructure from public and authorized sources. Choose one of 47 investigative Skills or describe the objective in plain language; Nexus reviews reputation and abuse observations for an IP address, examines domain registration, DNS and hosting relationships, researches credential exposure, links cited findings to inspectable evidence and leaves the assessment with the analyst.
Enrich the indicators behind an alert, investigate phishing and suspicious infrastructure and document credential exposure from one case-centered workspace. Nexus links cited findings to their sources, so the analyst who escalates and the reviewer who signs off see exactly what a conclusion rests on.
Challenges
Challenges for Threat Intelligence and SOC Analysts
Indicator enrichment scattered across browser tabs
One alert produces an IP address, a domain, a hostname and perhaps a sender address. Each goes to a different lookup service, the context is lost between tabs and the result is pasted into a ticket without its source or timestamp.
Reputation signals without dates or confidence
A listing can be months old, describe a shared hosting range or reflect a single automated report. Treating a raw score as a verdict produces false positives on legitimate infrastructure and false comfort on addresses nobody has reported yet.
Attacker infrastructure hidden behind redaction and shared hosting
Registration privacy, content-delivery networks and shared IP addresses make pivoting from one suspicious domain to related infrastructure slow and manual, and it is easy to overstate what a shared nameserver or hosting address proves.
Evidence that does not survive to the incident report
By the time an incident report or intelligence product is written, screenshots and pasted snippets have lost their source and retrieval time. A reviewer cannot check what a conclusion rests on, and the analysis cannot be re-opened when the indicator reappears.
Workflow
The Nexus workflow for Threat Intelligence and SOC Analysts
- 01
Define the objective
Name the indicators in scope — IP addresses, domains, hostnames, email addresses or handles — the alert or intelligence question they belong to and the relevant timeframe. Open a case so conversations, findings, notes and graphs stay together.
- 02
Choose a Skill or describe the investigation
Pick a focused Skill from the Skill Library — IP Threat Signals for an address in an alert, Domain Registration Intelligence for a suspected phishing domain, Breach Exposure Search for a corporate identifier, Public Forum and Community Mentions for public reports about a domain or handle — or describe the objective in the case conversation and let Nexus plan the work.
- 03
Discover relevant evidence
Nexus searches supported sources and retrieves available material. Every finding carries a citation that opens to evidence details with the original source, its context and the time it was retrieved.
- 04
Review findings critically
Separate supported findings from possible matches, contradictions and information gaps. A reputation signal can be stale or reflect shared infrastructure, an abuse report is an observation rather than attribution, and an address with no findings is not cleared.
- 05
Explore relationships
Add IP addresses, domains, hostnames and identifiers from evidence details to a relationship graph and examine whether indicators share registration, DNS or hosting context, without treating shared infrastructure as proof of common control.
- 06
Develop the assessment
Ask follow-up questions, produce a BLUF Situation Brief for the incident channel or leadership, or export selected case material as a structured PDF report. Include available custody records where enabled and verify indicators before operational use.

Skills used in this workflow
The investigative Skills these cases draw on most. Every Skill states the question it answers, what the investigator receives and what it cannot establish.
Outcomes
Outcomes for Threat Intelligence and SOC Analysts
- Indicators from an alert enriched in one case instead of a dozen browser tabs
- Reputation and abuse observations reviewed with their dates, confidence and limitations
- Suspected phishing domains examined with registration, DNS and hosting context
- Exposed corporate identifiers found with credentials redacted
- Related infrastructure connected on a relationship graph, with shared hosting kept distinct from common control
- Selected case records exported as a structured PDF report with a SHA-256 case-data hash

Frequently asked questions
What is agentic OSINT for threat intelligence and SOC analysts?
Agentic OSINT for threat intelligence and SOC analysts is open-source intelligence in which an AI agent plans and carries out multi-step investigations — source discovery, evidence retrieval, relationship analysis and reporting — against a defined question about an indicator, a domain or an exposure, while the analyst reviews and decides. In Nexus, an analyst enriches the IP addresses, domains and identifiers behind an alert, and cited findings link to inspectable source records rather than an unsupported score or summary.
Can Nexus enrich an IP address from a SIEM alert?
Nexus can enrich an IP address from an alert at a point in time. IP Threat Signals reviews available reputation and threat indicators with their dates, confidence and limitations, and IP Abuse History examines attributed abuse reports; both are Agency Skills. IP Network Location assesses approximate network and geographic context, and Reverse IP Relationships discovers hostname associations. Reputation signals can be stale or reflect shared infrastructure, and an address with no findings is not cleared.
How does Nexus help investigate a phishing or suspicious domain?
Nexus lets an analyst examine a suspicious domain with Domain Registration Intelligence, which reviews available registration details, relevant dates and redacted information, and DNS Posture, which examines public records and the infrastructure relationships they indicate. Reverse IP Relationships then discovers other hostnames on the same address. Related domains, hostnames and IP addresses can be added to a relationship graph from evidence details. Shared hosting or a similar name is a lead to corroborate, not proof of common control.
Does Nexus replace a threat intelligence platform, SIEM or SOAR?
Nexus does not replace a threat intelligence platform, SIEM or SOAR. Nexus is an agentic OSINT platform for investigation: each Skill answers a defined question from public and authorized sources at a point in time, and Nexus does not provide feeds, continuous monitoring or alerts. Threat intelligence and SOC teams use Nexus alongside their detection stack to investigate an indicator, a phishing domain or an exposed identifier, and to document the findings for the incident record or an intelligence product.
Is using Nexus for threat intelligence lawful and ethical?
Nexus works only with public and authorized sources. Nexus does not access private systems or accounts, does not guess email addresses and returns breach exposure findings with credentials redacted. Threat intelligence and SOC analysts remain responsible for a lawful basis, proportionality, their organization’s policy and any rules of engagement that apply to an incident. Nexus supports that discipline by treating abuse reports as observations rather than attribution and by keeping supported findings, possible matches, contradictions and information gaps separate.
Which Nexus plan fits a threat intelligence or SOC team?
Agency at €89 per month fits threat intelligence and SOC work best, because it includes all 47 Skills and 300 credits a month. Agency adds IP Threat Signals, IP Abuse History, Breach Pattern Analysis and Cross-Entity Correlation, plus end-to-end encrypted investigation notes. Pro at €59 per month includes 43 of the 47 Skills and 150 credits a month, covering Domain Registration Intelligence, DNS Posture, Reverse IP Relationships and Breach Exposure Search.
