Rapid7 MDR combines 24/7 SOC monitoring with threat hunting, investigation, containment, remediation, vulnerability context, and incident response. Its service can collect telemetry across endpoint, cloud, identity, email, network, and third-party technologies. Exposure information is incorporated into investigations so teams can prioritize vulnerabilities that are most likely to contribute to meaningful security incidents. Rapid7 also offers an enterprise MDR model for organizations requiring custom event sources, tailored detections, and closer collaboration between the provider's SOC and an internal security team.
Red Canary provides 24/7 managed detection and response across endpoints, identities, cloud systems, and other connected security sources. Its operating model combines behavioral analytics, automated threat hunting, expert investigation, and active remediation. The service is designed to work with existing security products rather than requiring organizations to replace an established technology stack. Response can be handled through automated playbooks, customer security teams, or Red Canary specialists depending on the engagement and incident.
eSentire operates a managed detection and response service through its Atlas platform and a 24/7 human SOC. The service correlates signals from endpoint, network, log, cloud, identity, and vulnerability data rather than treating each security layer independently. Response capabilities include host isolation, user suspension, investigation, and containment, while threat hunters and researchers support detection development. Organizations can integrate existing security technologies into the service instead of rebuilding their security environment around a single vendor stack.
Expel provides 24/7 security operations through a managed detection and response service designed to work with technology an organization already owns. Its Workbench platform connects endpoint, identity, cloud, network, SaaS, and other security sources while automation and AI collect evidence and accelerate investigations. Human analysts make security decisions and customers can follow investigations and response activity through the platform. This model can suit companies that want outsourced security operations without undertaking a major replacement of their current tools.
Integrity360 delivers its Aegis Managed Detection and Response service across networks, endpoints, on-premises systems, and cloud environments. Analysts provide around-the-clock monitoring, threat hunting, investigation, and containment when malicious activity bypasses preventive security controls. The wider managed-security portfolio also includes SIEM, EDR, XDR, NDR, cloud security, exposure management, and incident response, allowing MDR to form part of a broader operational security program rather than functioning as an isolated monitoring service.
net-devs provides enterprise software, cloud, and platform engineering that can support the technical remediation side of a managed detection and response program. Its teams work across Azure, AWS, and GCP, with infrastructure-as-code, Kubernetes, CI/CD, testing, and observability included in its broader engineering capabilities. Security is also built into its delivery process through security-focused QA, code review, architecture decisions, and production monitoring. When an MDR provider or internal SOC identifies vulnerable application behavior, infrastructure weaknesses, or production risks, net-devs can help implement code, cloud, and platform changes needed to address those findings.

SoftPro supports MDR-related environments primarily through cloud and application engineering rather than through a standalone managed security operations center. Its services include custom software development, web applications, cloud development, and ongoing work with Microsoft Azure and AWS environments. Security is incorporated into cloud architecture and application delivery through controls designed to protect infrastructure, applications, and data. SoftPro can therefore complement a dedicated MDR provider when security monitoring identifies issues that require application changes, cloud reconfiguration, access-control improvements, or infrastructure remediation.
