When an incident response (IR) engagement begins, the initial indicator feels like a starting point, but in practice, it’s rarely the full picture.
Behind the scenes, adversaries build clusters of infrastructure, registered in batches, aged across multiple hosting providers, and configured with redundancy in mind. The campaign that triggered an alert is almost always running on a broader foundation than the single artifact that surfaced in the SIEM. If remediation only covers what the investigation found during the active response, there is a real chance the attacker has left themselves a way back in.
This is the remediation gap. Not a failure of process or analyst skill, but a structural limitation of working from a single indicator outward with incomplete infrastructure visibility. Closing that gap requires a different starting point and a more proactive security platform.
The Problem With Indicator-First Remediation
Traditional IR workflows are built around the indicator. A domain fires an alert, the IP shows up in a log. The analyst enriches it, confirms it is malicious, and begins working outward from there. Blocklists get updated, the compromised asset gets contained and the report gets written.
The problem is what that process misses. By the time a single indicator surfaces, the adversary’s infrastructure has typically been live for weeks. The domain in the alert is a single node within a larger network of staging assets, backup infrastructure, and related domains, all of which are managed with consistent operational patterns. Standard enrichment tools confirm what the indicator is, but they rarely reveal everything it is connected to.

Infrastructure Has a Lineage
Every adversary campaign leaves a trail in the way its infrastructure was built and managed. Domains registered in the same window. Servers sharing certificate configurations. DNS records that resolve through the same hosting patterns. WHOIS data that clusters around consistent registration behaviors, even when providers change.
The Silent Push Context Graph was built to track exactly this. By continuously analyzing DNS, WHOIS, certificate data, host scans, and behavioral fingerprints across the internet every single day, it maps not just what infrastructure exists, but how it was created and how it is being managed. Those management patterns are what connect a single malicious indicator to the broader cluster it belongs to.
When an IR team starts an investigation with a domain or an IP address, the Context Graph can surface every related asset tied to the same infrastructure lineage: domains registered around the same time, IPs sharing server configurations, certificates rotating on the same schedule, and hosting patterns that match an adversary’s known operational TTPs. What would otherwise take hours of manual pivoting across fragmented tools becomes a complete infrastructure map available from the moment an investigation begins.
We built this because the industry needed it. Every security team, every threat intelligence function, every IR team is working harder than they should have to because the foundational data is not there. The Context Graph is that foundation.
What Complete Remediation Actually Requires
Remediating a breach means accounting for everything the adversary built, not just what they used during the active campaign.
That distinction matters because adversaries plan for detection. Backup infrastructure exists precisely because they expect some of their assets to get burned. If the remediation scope only covers the indicators confirmed during the active investigation, the attacker retains operational capability. The follow-on incident is not a new attack. It is the same one, running on infrastructure that was never found.
Complete remediation looks like this:
The Context Graph supports this at every stage. Years of DNS and WHOIS history make it possible to trace when infrastructure was first stood up and how it evolved. Real-time infrastructure relationships connect current indicators to assets that have not yet been used. The result is a remediation scope grounded in the adversary’s actual footprint, not the visible edge of it.
Faster Investigations, More Confident Findings
There is a secondary benefit that IR teams consistently report once this workflow is in place: investigations close faster, and the findings hold up better.
Manual pivoting is slow. Cross-referencing DNS records, WHOIS data, certificate histories, and hosting relationships across separate tools takes time that active incidents rarely allow. When that process is automated through the Context Graph’s APIs and SOAR integrations, the infrastructure map is built in the time it would previously take to enrich a single indicator. Analysts are not spending hours on correlation. They are spending that time on key decisions that actually require human judgment.
The confidence level changes too. When an IR report documents a full infrastructure cluster rather than a list of known-bad indicators, the remediation recommendations carry more weight. Leadership gets a complete picture. The blocklist reflects the adversary’s real footprint. And the security team doesn’t have to revisit the same threat three weeks later because a dormant asset came back online.
Remediation That Doesn’t Require a Follow-Up Incident
The goal of every IR engagement is a clean close. One that has no residual access, no dormant infrastructure waiting to reactivate, and no follow-on incident that traces back to something the initial investigation missed.
Getting there requires visibility that starts earlier in the infrastructure timeline and covers more of what the adversary actually built. The Context Graph gives IR teams that visibility, from the first indicator through the full cluster. The result is remediation that reflects the complete picture rather than the portion that happened to surface first.
Complete remediation starts with infrastructure intelligence. With the full picture in view, your team can close every door, before and after an attack, not just respond to the one that opened.

How does the Context Graph find related infrastructure?
The Silent Push Context Graph identifies related infrastructure by analyzing behavioral patterns adversaries use when building and managing campaigns. Instead of matching against a list of known-bad assets, it looks at how infrastructure is created and operated, examining domains registered in the same window, servers sharing certificate configurations, IPs resolving through consistent hosting patterns, and WHOIS records clustering around the same registration behaviors. When those patterns align with known adversary TTPs, the Context Graph connects the dots across the full cluster. A single confirmed indicator becomes the entry point into every asset built and managed alongside it, whether those assets have been used yet or not.
What data sources does it use?
The Context Graph aggregates data across five primary layers. Passive-Aggressive DNS (PADNS) actively re-resolves every hostname Silent Push can find daily, building a continuous record of DNS changes across the internet rather than relying solely on passive observation.
WHOIS and zone file monitoring tracks ownership and registration changes in real time. Host scans and SSL certificate analysis identify unique server configurations and track their evolution.
Honeypot data captures direct interaction from adversarial reconnaissance activity. And our Traffic Origin sensors analyze anomalous communication patterns to attribute proxy and VPN traffic to its actual country of origin. Together, these layers give IR teams a unified view of infrastructure lineage that no single data source can provide.
How long does an investigation take with the Context Graph?
Significantly less time than a traditional manual workflow. Pivoting across DNS records, WHOIS history, certificate data, and hosting relationships through separate tools is a process that can take hours on a single indicator. With the Context Graph, that correlation happens automatically. APIs and pre-built SOAR integrations mean the infrastructure map is built in the time it would previously take to enrich one domain.
IR teams consistently report that their investigations close faster and with greater confidence, because the full cluster is visible from the start rather than assembled piece by piece under time pressure.
