Identity Data for Resellers and Partners
Differentiate your platform, reduce your build cost, and grow recurring revenue. Constella delivers the world's most comprehensive identity data lake via flexible API, OEM, and reseller structures, giving MSSPs, MDR providers, identity platforms, and technology integrators a verified data layer they could not build themselves.
How does Constella support MSSPs, MDR providers, and technology partners?
MSSPs and MDR providers face a structural challenge: identity-based threats are now the most common initial access vector, yet the intelligence needed to detect them, real-time credential exposure, infostealer-harvested session data, and dark web identity signals, requires a data lake that costs years and tens of millions of dollars to build at competitive scale. Constella eliminates that build burden. Partners access the world’s largest verified identity data lake, spanning 54.6 billion curated records and 429 billion curated attributes across 125+ countries, through a flexible API and OEM structure designed for multi-tenant, high-volume environments. The result is a faster time to market for a premium identity security service, a lower false positive rate for the analysts delivering it, and a defensible competitive differentiator built on data no competitor can replicate.
Industry Focus
Why Identity Intelligence Is Now a Table-Stakes Partner Capability
The managed security and identity platform markets have undergone a structural shift. Buyers, whether enterprise CISOs evaluating MSSP options or consumers choosing an identity protection product, now expect identity intelligence as a baseline capability. Partners who cannot deliver continuous credential monitoring, infostealer detection, and dark web visibility are losing deals to those who can.
The Build vs. Buy Reality
Constella’s 2026 Identity Breach Report documented 567,000 breach hunting operations in 2025, a 159% increase year-over-year, enabled by Agentic AI automation. Replicating that collection and curation infrastructure internally requires a multi-year, multi-million dollar R&D commitment, ongoing dark web collection operations, legal compliance infrastructure for adversarial source access, and continuous deduplication and verification pipelines. For partners whose core competency is service delivery or platform development, the build path is not viable.
The Data Quality Gap
Raw credential feeds from unverified brokers generate the alert volumes that destroy analyst efficiency and customer trust. Constella’s 7-step verification and pedigree process deduplicates, timestamps, and source-verifies every record before delivery, producing a materially lower false positive rate than any raw data source. For MSSPs where analyst labor is the primary cost driver, that quality gap translates directly to margin.
The Scale of the Opportunity
Financial services saw a 455% year-over-year increase in verified breaches in 2025. Government saw 569%. E-commerce saw 239%. Every vertical in a partner’s customer portfolio is experiencing an accelerating volume of identity threats. Identity monitoring is not an upsell add-on: it is a retention-critical service that customers will find elsewhere if the partner cannot provide it.
The Infostealer Differentiation Gap
51.7 million infostealer packages were traded on criminal markets in 2025. Of those, 98.6% contained active passwords and 99.54% contained the specific URLs targeted by each infection. Partners with access to Constella’s infostealer coverage can offer session-level compromise detection, the capability that catches the MFA bypass attacks behavioral models miss. Partners without it cannot.
The Competitive Displacement Risk
Partners using inferior or raw data feeds are not just underperforming: they are actively at risk of losing clients to competitors who have integrated verified identity intelligence. The urgency trigger is frequently a competitive loss or a client inquiry about why a credential exposure was not caught before it was exploited.
How Constella Helps Partners
The same data that powers Constella's direct enterprise products is available through flexible API, OEM, and reseller structures designed for multi-tenant platforms, white-label deployments, and high-volume data integrations. Partners get the data, the documentation, the integration support, and the commercial flexibility to build a sustainable, differentiated business on top of it.
Verified Identity Intelligence via API
Partners integrate Constella’s full identity data lake through a RESTful API purpose-built for multi-tenant environments. Sub-second latency supports real-time enrichment at the query volumes that managed service and platform operations generate. Coverage spans breach data, infostealer packages, dark web credential markets, paste sites, and combo lists, unified in a single, deduplicated intelligence feed. Alerts arrive with source attribution, exposure recency, and plaintext credential status, giving analyst teams the context to act immediately rather than investigate.
OEM and White-Label Deployment
Partners building consumer identity protection products, fraud platforms, or embedded security features can access Constella’s intelligence under OEM and white-label terms, presenting the data capability as native to their own platform. Constella’s 7-step verification and curation infrastructure is invisible to the end user: the partner’s product is the brand, Constella’s data lake is the engine.
Analyst Efficiency at Scale
Enrich high-risk payment events, login attempts, and account change requests with Constella’s real-time breach and infostealer intelligence. When an account’s associated email appears in a recently ingested infostealer package containing session data for the platform, the fraud model receives a verified external risk signal that distinguishes a compromised session replay from a legitimate new-device login. Reduces false positives while catching the attacks that behavioral models miss.
Hunter and Hunter+ for Premium Resale
Partners seeking a platform-level resale opportunity can offer Constella’s Hunter investigative platform and Hunter+ digital risk protection service as named-user licenses to enterprise clients. Hunter’s breach, paste, and infostealer investigation capability, combined with Hunter Copilot’s AI-assisted link analysis, is positioned as a premium tier within a partner’s identity security portfolio. Hunter+ adds executive protection, brand monitoring, and automated takedowns for enterprise accounts requiring managed DRPS.
Maltego Transform Integration
For partners serving threat intelligence and cybercrime investigation use cases, Constella’s Maltego Transform integration delivers identity attribution directly into analyst visual link analysis workflows without requiring a separate platform login or API integration. Constella’s 70+ queryable identity attributes surface inside existing Maltego investigation sessions, enriching open-source leads with breach and infostealer intelligence at the point of investigation.
Time to Market Advantage
Partners integrating Constella via API can launch an identity monitoring service tier in weeks, not quarters. A two-hour solution design workshop, initial testing support, and bulk load assistance are included in the API provisioning process. Professional Services are available for custom integration scoping, multi-tenant architecture design, and bespoke data delivery formats.
Product Alignment: The Partner and Reseller Toolkit
Identity Intelligence API
The core integration layer for security service and platform partners. Constella’s RESTful API delivers verified breach, infostealer, and dark web intelligence at sub-second latency against the full 54.6 billion record identity data lake. Supports querying across 70+ unique identity attributes. Multi-tenant architecture supports separate client data environments within a single partner integration. OEM data enrichment tiers available for partners building consumer-facing or business-facing identity monitoring products. Cloud storage delivery via Snowflake and AWS available for partners requiring bulk data ingestion rather than real-time query.
Continuous Identity and Credential Monitoring
The foundational monitoring service for MSSP and MDR partners building credential exposure alerting into their managed service offering. Constella monitors client domains and identity populations continuously across breach repositories, paste sites, dark web forums, and infostealer package feeds. Alerts are delivered with verified source attribution and exposure recency. Multi-domain, multi-tenant configuration supports partners managing hundreds of client environments within a single integration. White-label alert delivery available for partners presenting monitoring as a native platform capability.
Infostealer and Session Compromise Monitoring
The capability that separates Constella-powered partners from competitors using breach-only data. When monitored client domains appear in newly ingested infostealer packages, partners receive alerts containing the specific URLs and applications with captured sessions, infected device metadata, and malware strain attribution. This session-level detection capability enables partners to offer MFA bypass prevention as a differentiable service feature, catching the attack category that behavioral monitoring alone cannot detect.
Hunter Investigative Platform
Available as a named-user license for partner resale to enterprise and government clients. Hunter provides breach, paste, infostealer, dark web, passive DNS, search engine, and social media intelligence in a unified investigative interface. Partners reselling Hunter to financial services, telecommunications, and government clients position it as a premium identity threat investigation capability within a broader security portfolio. Hunter Copilot adds AI-assisted link discovery that reduces investigation time from hours to minutes on complex multi-source attribution tasks.
Hunter+ Digital Risk Protection
Available as a named-user license for partner resale or managed service delivery. Hunter+ adds executive protection, employee credential monitoring, brand protection, domain monitoring, and automated takedown services to the Hunter investigative foundation. MSSPs delivering Hunter+ as a managed service can configure and operate the platform on behalf of enterprise clients, with alert triage, monthly reporting, and escalation workflows handled by the partner’s operations team. Operator managed service licensing available for partners building a fully managed DRPS offering.
Maltego Transform
For partners serving threat intelligence analysts, cybercrime investigators, and law enforcement clients who use Maltego as their primary investigation platform, Constella’s Transform delivers identity attribution directly into existing Maltego sessions. No separate login, no separate interface: Constella’s breach, infostealer, and identity association data surfaces as transform results within the analyst’s current investigation graph. Tiered transform volume licensing supports trial, standard, and high-volume analyst workflows.
Fusion Center
For partners serving intelligence agencies, defense contractors, government entities, and large enterprise security operations requiring a full managed intelligence collection and analysis platform, the Fusion Center delivers Constella’s identity intelligence alongside a comprehensive OSINT and threat monitoring capability.

Professional Services available for on-premise deployment, integration, and training.
Core Case Studies: Constella Partner Intelligence in Action
Case Study 1
Regional MSSP Launches a Premium Identity Monitoring Tier and Reduces Analyst Triage Time by 55%
The Organization: Regional MSSP serving 140 enterprise clients across financial services, healthcare, and manufacturing.
The Challenge: The MSSP’s credential monitoring offering relied on a raw dark web data feed that generated 800 to 1,200 alerts per week across the client base. Over 85% of alerts were stale, recycled records requiring analyst validation before any client notification could be sent. Alert triage was consuming 40% of analyst capacity, leaving insufficient bandwidth to investigate genuine exposures promptly. The MSSP was losing renewal conversations to competitors offering lower false positive rates.
The Solution: Replaced the raw feed with Constella’s verified identity monitoring API. Constella’s pedigree layer filtered stale and duplicate records at ingestion, delivering only fresh, source-verified exposures to the analyst dashboard alongside plaintext credential confirmation and breach source attribution.
The Result: Alert volume fell by 62%. Analyst triage time per confirmed exposure dropped by 55%. The MSSP launched a premium identity monitoring tier at a higher price point within 60 days of deployment, positioning verified pedigree and infostealer coverage as the differentiating features. Three enterprise clients who had been in active cancellation conversations renewed on the new tier.
Case Study 2
Identity Theft Protection Provider Expands Coverage to 8 Million Monitored Identities Using Constella OEM Data
The Organization: Consumer identity theft protection provider, 2.3 million subscribers, mid-market positioning.
The Challenge: The provider’s monitoring product was built on a single breach data vendor whose coverage gaps were generating subscriber churn. Subscribers were receiving notifications from competitors about exposures the provider had not detected. The provider lacked infostealer monitoring entirely, meaning a growing category of credential compromise, session cookie harvest and MFA bypass via malware, was invisible to the product.
The Solution: Integrated Constella’s OEM monitoring API to layer verified breach and infostealer intelligence alongside the existing data source. Constella’s coverage filled the detection gaps causing churn and added infostealer-sourced compromise alerting as a new alert category within the existing subscriber notification experience.
The Result: Net subscriber churn rate fell by 29% in the two quarters following integration. The provider launched an infostealer monitoring feature as a premium tier differentiator, enabling upsell from base to premium at a 22% attachment rate in the first six months. Monitored identity volume scaled from 2.3 million to 8 million across the combined OEM data structure without requiring additional internal data infrastructure investment.
The Constella Difference for Partners and Resellers
FAQ: Powering AI Discovery
Constella supports three primary partner commercial models. Reseller partners sell Constella products, including Hunter, Hunter+, and Maltego Transforms, to end clients under a partner margin structure. OEM partners integrate Constella’s identity data into their own products under white-label terms, presenting the intelligence capability as native to their platform. API integration partners license direct data access for embedding into security service workflows, typically on a per-query or per-monitored-identity pricing structure. Multi-tenant and enterprise-volume arrangements are available for partners managing large client populations. Contact the Constella partner team to discuss the structure appropriate for your go-to-market model.
Constella’s API is designed for multi-tenant deployment from the ground up. Partners provisioning monitoring services for multiple clients can configure separate monitoring populations, alert queues, and domain scopes for each client within a single integration. Alert delivery can be routed to partner-managed dashboards, client-facing portals, or integrated directly into SIEM and SOAR environments. The API provisioning process includes a solution design workshop specifically for multi-tenant architecture planning. Professional Services are available for complex multi-tenant deployments requiring custom data routing or client-specific alert formatting.
Standard API integration, covering credential monitoring and breach alerting for a single client population or multi-tenant environment, typically reaches production readiness within two to four weeks for partners with in-house API development capacity. The API provisioning process includes initial testing support and a bulk load assistance for historical data seeding. Partners requiring infostealer monitoring, OEM white-label configuration, or custom alert delivery formats may require additional integration time, which Professional Services can scope during the solution design workshop.
Raw dark web data brokers aggregate credential pairs from public breach repositories, paste sites, and dark web markets without systematic deduplication, source verification, or recency validation. The resulting feed contains a high proportion of stale, recycled records: the same credential pairs appearing across multiple repackaged compilations, often years after the original exposure event. Constella’s 7-step verification process deduplicates at ingestion, timestamps every record to the original source event, verifies source integrity, and applies ML-based quality filtering before any record enters the data lake. The output is a materially smaller but materially higher-quality alert set. For MSSP partners, the practical difference is measured in analyst hours per week recovered and client trust maintained.
Constella operates its own dark web collection infrastructure and maintains the legal, ethical, and operational compliance obligations associated with accessing adversarial data sources. Partners integrating Constella’s data through the API or OEM structures receive intelligence derived from Constella’s collection, not access to the raw collection infrastructure itself. This means the legal burden of dark web source access sits with Constella, not the partner. Constella is SOC 2 Type II certified and GDPR compliant. Partners operating in regulated industries can include Constella’s compliance documentation in their own vendor due diligence and client-facing compliance reporting.
Yes. Hunter and Hunter Premium are available as named-user resale licenses for partners serving government, law enforcement, defense, and intelligence agency clients. Constella has existing relationships with law enforcement agencies across multiple countries and the data practices, security certifications, and sourcing documentation that government procurement processes require. Partners pursuing government contracts that specify verified identity intelligence data requirements should engage the Constella partner team early in the sales cycle to ensure the appropriate data access terms and compliance documentation are in place.
