About Archer

Archer sells a governance, risk and compliance platform that connects enterprise risk, compliance, audit, AI governance, ESG, third-party risk and resilience on shared data and one reporting layer. Archer brings risk, controls, obligations and evidence into one governed system. Archer says regulatory change moves faster than teams can interpret, assess and operationalize it. More than 1,500 organizations run on Archer, including half the Fortune 500.[2][3]

Archer Evolv adds AI-powered intelligence to an existing GRC program and connects regulatory change obligations, controls, policies and assurance evidence. Archer Evolv can be deployed standalone or alongside Archer GRC, on-premises or SaaS. Archer describes a system of record, a system of intelligence and a system of outcomes as one connected foundation that uses existing permissions and audit trail. Archer Evolv turns data from the GRC environment into governed intelligence with AI operators.[3][6]

Workplace is where Evolv operators run, and each operator handles one governed task, such as mapping a new obligation to the controls it touches. In Archer, a reviewer approves the result of an operator before it reaches the customer's controls. Archer Evolv operators run third-party reviews end to end, monitor vendors between assessments and enforce the customer's requirements. Archer Evolv operators monitor technology risks, controls and issues, enforce the customer's standards and rank what needs attention first. Archer monitors 8,000+ regulatory sources across 180 jurisdictions, from SEC and FINRA to DORA, and flags what applies to a business.[3][4]

Archer Evolv assesses each citation against a customer's jurisdictions, products and legal entities. A wizard in Archer captures a customer's jurisdictions, entities, products and themes, and assesses each incoming citation against that profile. Archer parses citations, rulebooks, statutes and a customer's own policies into discrete obligations, each linked to its type, its theme and its source citation. Archer clusters up to 10,000 obligations per assessment by meaning. Archer compares a customer's obligations against the controls it already holds, names the gaps and conflicts and proposes a resolution. Archer Evolv extracts obligations, maps them to controls and business units, routes the assessment to named owners and publishes the result into Archer.[5]

Archer turns regulations and a customer's policies into live AWS Bedrock guardrails that are enforced before the model is invoked. Guardrails are deployed as drafts and go live only after the customer approves them. Traffic is evaluated against guardrails before inference inside the customer's AWS account, and violations are blocked and logged as a governed control breach. Every deployed guardrail is tested on a cycle against the control the customer approved. Findings from each violation route into Archer issue management workflows. Prompt content, model responses, documents, embeddings, customer PII and model weights do not reach Archer, and only the violation event does.[6]

Archer's IT and security risk offering has nine interconnected use cases with workflows that move findings and controls from assessment through closure. Archer's IT risk register catalogs the organization and its IT assets and logs each IT risk against the systems it touches. Archer tests IT controls on a project schedule and pulls in results from automated systems. Archer ranks threats and vulnerabilities by what they put at risk in the business, using asset context and scan results. Archer ships current security frameworks and control catalogs with the use case, including the ISO 27000 series, COBIT 5, the NIST 800 series and PCI DSS. Archer rolls test results up to the primary control and reports compliance for each control set separately. Archer stores evidence in a versioned repository as tests run, tied to the control and the standard it serves.[7][8]

Archer gives financial institutions one connected view of obligations, controls and risk. Archer connects regulatory compliance, third-party risk, operational risk and IT security in one system. Archer helps government agencies unify FedRAMP, CMMC and FISMA obligations. Every control in Archer links back to the exact FedRAMP, CMMC or FISMA requirement it satisfies, and every AI output goes through Expert-in-the-Loop review. Archer tests controls against live evidence, flags a gap as it appears, routes it to an owner and keeps a time-stamped record. Archer translates risk into financial terms based on modeled loss exposure and stated assumptions. Archer states SOC 2 Type II and ISO 27001 and describes 25+ years as a system of record. The Archer Vulnerability Response Team coordinates the response and disclosure for all product vulnerabilities reported to Archer.[2][3][4][6][7][8][9][10]
