Managed Detection and Response Services (MDR / EDR / NDR / XDR)

Managed Detection and Response (MDR) is a 24x7 security monitoring service that detects threats in your environment, investigates them, and takes action before they cause damage. APT Security Management, based in North Charleston, SC, provides MDR services to businesses across the United States using a prepaid token-based model with no long-term contract required. Whether your organization needs endpoint detection (EDR), network detection (NDR), or full cross-environment coverage (XDR), APT builds and manages a detection layer tailored to your environment.

Who Needs MDR Services?

Most organizations don't have the staff or tools to monitor their environment around the clock. Threats don't respect business hours, and by the time an alert gets reviewed the following morning, damage has already been done. MDR fills that gap by keeping a trained security team watching your systems at all times.

Small businesses and growing companies are especially exposed. They often rely on basic antivirus software or unmonitored firewalls, which don't provide visibility into what's actually happening on endpoints, in network traffic, or across cloud infrastructure. MDR gives those organizations enterprise-grade monitoring without requiring them to hire a full security team.

Organizations in regulated industries have additional motivation. Frameworks including HIPAA, PCI-DSS, SOC 2, NIST CSF, and CMMC either require or strongly encourage continuous security monitoring and documented incident response. MDR supports your ability to demonstrate compliance and respond quickly when an auditor asks for evidence.

Why APT

APT uses a prepaid token system instead of traditional monthly retainers. You buy tokens, apply them to the services you need, and aren't locked into a 12-month commitment for services you may not use. Tokens are valid for 12 months from purchase and can be spent across any APT service.

Our team holds certifications including OSCP, CISSP, and CEH. These aren't entry-level positions staffing a tier-1 SOC queue. When your environment triggers a detection, the people reviewing it have real operational experience.

APT works with proven partners including Sophos, Bitdefender, Trend Micro, and Fortinet. We recommend technology based on what fits your environment, not based on vendor margins or commission agreements.

Our three engagement tiers (ravenWing, ravenGuard, and ravenSentinel) let you choose how much visibility and collaboration you want. Whether you need simple email-based updates or a custom dashboard integrated into your internal systems, there's a tier that fits.

Every PTaaS engagement is delivered through one of our three engagement models:

Frequently Asked Questions

What is Managed Detection and Response (MDR) and how does it work?

MDR is a service where a team of security professionals monitors your environment continuously, investigates alerts, and responds to confirmed threats on your behalf. It combines detection technology deployed in your environment (on endpoints, networks, and cloud systems) with human analysts who review and act on what those tools find. APT handles the monitoring and investigation so your team can focus on running the business.

How is MDR priced at APT? What does it cost in tokens?

APT uses a prepaid token system. The token cost for MDR depends on the size of your environment, how many endpoints and systems are in scope, and which coverage layers you need (EDR, NDR, XDR, or a combination). Contact us or book a free consultation and we'll provide a specific token estimate based on your environment.

How long does it take to get MDR up and running?

Onboarding timelines vary based on environment complexity, but most engagements are fully operational within one to two weeks. This includes deploying agents, connecting integrations, and confirming escalation contacts and response playbooks. The discovery call and scoping process typically takes a few days before onboarding begins.

What is the difference between MDR, EDR, NDR, and XDR?

EDR (Endpoint Detection and Response) covers individual devices like laptops and servers. NDR (Network Detection and Response) monitors traffic between devices and looks for suspicious patterns in your network. XDR (Extended Detection and Response) correlates data across endpoints, networks, cloud, and email into a unified view. MDR is the managed service layer on top of any of these: instead of your team operating the tools, APT's team does it for you.

What happens when a threat is detected?

APT's team investigates the alert, determines whether it's a confirmed threat or a false positive, and takes action based on the escalation playbook agreed on during onboarding. Depending on your environment and authorization level, this can include isolating an affected endpoint, blocking a process, or escalating to your internal IT contact for remediation. Every confirmed incident is documented with a full timeline of actions taken.

Do you offer ongoing support after the initial setup?

Yes. MDR is a continuous service, not a one-time engagement. As long as your tokens are active, monitoring continues around the clock. APT also provides monthly reporting and is available for strategy reviews at the ravenGuard and ravenSentinel tiers.

What types of businesses does APT work with for MDR?

APT provides MDR to businesses of all sizes across the United States, from small businesses with a handful of endpoints to enterprises with complex, multi-environment infrastructure. Organizations in healthcare, finance, SaaS, retail, and government contracting are common clients, particularly those with compliance requirements that call for continuous monitoring.
