AI Defence / Remedy architecture
Security categories overlap. Mature platforms already combine detection, prevention, access decisions and automated response. This comparison explains the questions each category helps answer and where Remedy’s planned authority and evidence model fits.
Antivirus commonly contributes malware prevention. EDR adds endpoint observations, investigation and response; XDR connects signals across more domains. Managed detection and response also includes an operating service. Products can span all of these, so a simple “detects versus fixes” comparison would misrepresent the market.
Microsoft Defender, CrowdStrike Falcon, SentinelOne, Sophos and Huntress illustrate different endpoint packages and operating models. Remedy is intended to work alongside established prevention and response. It does not claim their detection performance, telemetry scale, staffed operations or production maturity.
The following categories describe emphasis, not hard product limits. A vendor may supply several capabilities together. Ask what actually runs, which platforms and paths it covers, how it is operated and which evidence validates the result.
| Category | Usual emphasis | Question for the Remedy design |
|---|---|---|
| Antivirus / EDR / XDR | Prevention, telemetry, investigation and response | How do endpoint observations inform bounded authority and readmission? |
| Sandbox / task isolation | Analyse or contain execution in a separate environment | How do provenance, current certification and output promotion affect the task? |
| Browser isolation / RBI | Run active web content behind a stronger boundary | When is isolation needed, and what happens to downloads and credentials? |
| Zero Trust / ZTNA | Contextual access to specific resources | How do content state and remediation evidence influence that access? |
| NAC / device trust | Device admission, posture and network restrictions | What evidence supports quarantine and subsequent recertification? |
| Microsegmentation / firewall | Restrict unwanted communication and exposure | Which minimum network authority is justified for the current state? |
| File integrity / configuration monitoring | Detect and explain changes to approved state | Does the change invalidate certification or require isolation? |
| Deception / honeypots | Observe interactions with instrumented decoys | How does the event affect risk and an authorised response? |
| Vulnerability management / validation | Prioritise exposure and test control effectiveness | Which fresh evidence supports closure after corrective work? |
| SOAR / response orchestration | Coordinate cases, tools and permitted playbooks | How are action scope, approval and verification linked? |
Cloudflare provides browser isolation alongside access controls. Zscaler spans access and browser security, and HP Sure Click uses task containment. These establish that neither stronger browser boundaries nor disposable isolation is a new primitive invented by Remedy.
Cisco ISE documents posture-based access and quarantine, while Illumio focuses on communication policy and segmentation. Remedy’s proposed distinction is a consistent lifecycle across content, applications, devices and corrective actions. Its specific integration and operational results still need to be demonstrated.
Tripwire describes file-integrity change context; Darktrace includes network detection and response; FortiDeceptor provides instrumented decoys. Firewall platforms from Cisco, Fortinet and Palo Alto Networks govern traffic at supported enforcement points. Cymulate addresses security validation, while Cortex XSOAR coordinates response workflows.
It would be inaccurate to say these categories only produce alerts or never automate remediation. Remedy should be assessed on its own proposed evidence relationships, supported actions, acceptance results and operational boundaries. No category-wide superiority or comparative benchmark is claimed.
Public endpoint offerings may be priced per device, per endpoint or per user, with different annual commitments and managed-service options. Identity/access services may use user-based tiers; firewalls and enterprise suites can combine appliances, subscriptions and modules. Quote-based products require the actual deployment scope.
A low headline rate cannot establish the full cost of equivalent coverage. Compare licensing prerequisites, server entitlements, support, operational staffing, integrations and required add-ons. Remedy Defence commercial terms need direct confirmation; software-repair pricing from the related Remedy product is not presented as a Defence subscription.
Ask for the accepted candidate build, supported platforms and current implementation evidence. Identify the security question, relevant enforcement boundaries and the precise role of any existing tools. Then establish the permitted actions, operator responsibilities, failure handling and evidence for the result.
Vendor pages were reviewed on 12 September 2026 for category positioning. Their public descriptions are sources about their offerings, not independent performance tests or evidence of a Remedy partnership. The Remedy capabilities discussed here remain development or architecture as shown on the product status page.
That is not the intended positioning. Remedy is being designed to coordinate measured trust, authority and evidence across appropriate existing controls. Actual integration support must be confirmed.
