Managed detection and response combines security telemetry, continuous monitoring, investigation, threat hunting, and response to help organizations identify attacks before they develop into larger incidents. The category includes dedicated MDR vendors with 24/7 security operations centers as well as engineering and cybersecurity partners that handle adjacent work such as SIEM implementation, cloud security, application hardening, incident response processes, and remediation. Buyers that need full outsourced SOC coverage should verify that a provider explicitly offers continuous monitoring and managed response, while engineering-led providers can be useful when security findings need to translate directly into application, infrastructure, or cloud changes.
Gilzor approaches security through software engineering, application assessment, QA, architecture, and ongoing product maintenance rather than operating as a conventional MDR vendor. Its work includes secure application development, technical audits, security-focused testing, troubleshooting, infrastructure work, and post-launch support. The company has also published security-focused service material covering website and application protection.
This model is most relevant when detection or security findings need to be followed by changes to application code, architecture, deployment, or infrastructure. Companies requiring a dedicated 24/7 SOC would generally combine this engineering capability with specialized MDR technology or a managed security provider.

Active Response capabilities allow the provider to take containment actions across supported endpoint, identity, email, network, and cloud technologies. Customers also receive a Concierge Security Team that provides ongoing context and security guidance.
A-listware offers managed IT and cybersecurity services alongside software development and infrastructure work. Its managed security capabilities include vulnerability and security audits, penetration testing, security program assessment, infrastructure protection, cloud management, application support, and security-focused operational work.
The company's cybersecurity offering has also been described around threat monitoring, incident response, security audits, compliance management, and Cyber Security as a Service. This places A-listware closer to a managed security model than a development-only provider, although organizations seeking a traditional MDR engagement should confirm the required SOC coverage, telemetry integrations, and response scope during procurement.
Sophos operates a dedicated Managed Detection and Response service combining 24/7 security analysts, threat hunters, incident responders, detection engineers, threat researchers, automation, and AI-assisted security operations. The service is vendor-agnostic and can integrate data from hundreds of supported security and IT tools.
Its MDR team investigates alerts, conducts proactive threat hunting, and can contain and remove confirmed threats. Sophos also supports different service and response models, making the offering applicable to organizations that want either a heavily outsourced security operation or support for an existing internal security team.
SentinelOne provides 24/7 managed detection and response through Wayfinder MDR. Security analysts continuously monitor customer environments, investigate alerts, perform threat hunting, and respond to confirmed attacks. Coverage can include endpoints, cloud workloads, identity systems, and supported third-party integrations.
The service uses SentinelOne's Singularity platform together with security analysts, threat intelligence, and AI-assisted investigation. Response actions can include killing malicious processes, isolating endpoints, and rolling back unauthorized changes according to the customer's configured response policy.

Net-devs is an enterprise software engineering company rather than a dedicated MDR provider. Its work covers enterprise application development, cloud and platform engineering, infrastructure-as-code, testing, observability, deployment, and continuing software evolution. Security and correctness are incorporated into its engineering and QA processes.
The company is relevant to detection and response programs when security teams need engineering support to implement logging, improve application architecture, harden cloud environments, correct vulnerabilities, or remediate weaknesses identified by an MDR platform. Its cloud work spans Azure, AWS, and Google Cloud.
Palo Alto Networks provides Unit 42 Managed Detection and Response using Cortex XDR. Unit 42 analysts work with security telemetry from endpoints, networks, cloud systems, and identity sources, applying threat intelligence, behavioral indicators, analytics, investigation, and response capabilities to identify attacks across connected environments.
This approach is particularly relevant to organizations already invested in Cortex XDR or other Palo Alto Networks security technologies. The MDR service connects the company's security platform with Unit 42's threat intelligence and incident-response expertise.

SoftPro is a Warsaw-based custom software, cloud, and AI engineering company. Its service portfolio focuses on software development, Microsoft technologies, Azure, cloud projects, modernization, migration, and continuing maintenance rather than a dedicated managed SOC. The company provides ongoing technical support for the systems it develops and works with cloud environments where operational monitoring and security controls form part of application management.
For MDR-related projects, SoftPro is more applicable as an implementation and remediation partner. Internal security teams or specialist MDR providers can identify issues, while SoftPro's engineers address application, integration, cloud, or software changes required to reduce exposure.
21century.tech is an AI-native software studio focused on rapid production software development. Senior engineers handle architecture, security judgment, code review, QA, and production ownership while AI tools assist with code generation, testing, documentation, and refactoring.
The company does not present itself as a dedicated MDR or SOC provider. Its role in a security program is more likely to involve application remediation, refactoring, secure implementation, CI/CD, or engineering changes following a security review. This can make it useful when vulnerabilities or operational weaknesses require development work rather than continued alert monitoring.
Red Canary focuses on operating as an extension of internal security teams rather than simply forwarding alerts. Its MDR service provides 24x7 security operations, behavioral detection, threat hunting, investigation, and response across endpoints, identities, cloud environments, and other supported data sources.
The provider is particularly relevant to organizations that already have capable security tooling but need additional detection engineering and analyst capacity.

Its broader cybersecurity portfolio also includes related security services that can complement ongoing managed detection work.
Rapid7 combines managed detection and response with exposure and vulnerability context. Its MDR service brings together endpoint, cloud, identity, email, network, and third-party telemetry while feeding vulnerability and asset risk information into investigations. That context can help analysts distinguish higher-risk activity from lower-priority security noise.
Rapid7 analysts support investigation, containment, remediation, threat hunting, and broader security guidance. The approach can be useful for organizations that already use exposure management or vulnerability data and want those findings connected directly to day-to-day security operations rather than managed in a separate process.
Managed detection and response has expanded well beyond endpoint alert monitoring. Dedicated MDR providers increasingly combine endpoint, identity, cloud, network, SaaS, and third-party telemetry with continuous investigation, threat hunting, containment, and remediation. At the same time, detection alone does not fix insecure application code, cloud architecture, deployment processes, or configuration weaknesses, which creates an important role for security-aware engineering partners. When evaluating a full MDR service, organizations should clarify SOC availability, telemetry coverage, response authority, integration requirements, escalation procedures, and exactly which remediation actions are included. Where engineering firms are used alongside an MDR provider, responsibilities between monitoring, incident handling, infrastructure changes, and software remediation should be defined before an incident occurs.
