Detection & development, weekly
Product updates, security research, and Zero Trust engineering from the LightEDR team.
From FULL to QUARANTINE: what happens when an endpoint's trust drops
A deep dive into how Zero Trust endpoint trust levels work in practice - what triggers a trust downgrade, how the SOC sees it, and what the endpoint experiences.
Read postEDR vs SIEM vs XDR: choosing the right threat detection stack
EDR, SIEM, and XDR solve different problems. This guide breaks down what each tool actually does, where they overlap, and how to choose for a lean SOC team or MSSP.
Read postCase study: catching a crypto-miner with behavioural and network signals
How real-time behavioural detection and network telemetry exposed a hidden crypto-miner on a development endpoint that antivirus completely missed.
Read postHow insider threats exploit trusted endpoints - and how Zero Trust stops them
Insider threats exploit the implicit trust that perimeter security grants by default. Here is how Zero Trust continuous verification exposes anomalies that legacy EDR misses.
Read postNatural language threat hunting: querying your EDR with AI
Most SOC analysts can't write complex detection queries. Natural language threat hunting changes that - here's how AI-powered queries work in practice.
Read postCompliance and EDR: what your security logs must prove
GDPR, PCI DSS, and ISO 27001 all demand evidence of detection and response. Here is what your EDR logs need to capture - and what most platforms miss.
Read postWriting detection rules for process injection on Linux
Process injection on Linux takes multiple forms - ptrace, /proc/mem writes, LD_PRELOAD hijacking. Here's how to write detection rules that catch each variant.
Read postmTLS vs API key auth: the security case for certificate-based access
API keys are easy to set up but hard to keep secure. Here's why mutual TLS gives SOC and MSSP teams a fundamentally stronger authentication model for agent-to-server comms.
Read postZero Trust continuous verification: why periodic re-auth isn't enough
Periodic re-auth checks trust at login and forgets everything that changes after. Here's why continuous Zero Trust verification is fundamentally different.
Read postDetecting lateral movement with behavioural event monitoring
Lateral movement is often the longest and noisiest phase of an attack. Here's how to detect it using MITRE ATT&CK-mapped behavioural signals - before the damage is done.
Read postThe five trust signals: how LightEDR scores endpoint trustworthiness
LightEDR continuously evaluates five trust signals - certificate identity, behaviour, network context, session state, and posture - to determine what access each endpoint deserves.
Read postWhy most EDRs are over-engineered for small SOC teams
Enterprise EDR platforms are built for Fortune 500 security teams. Here's why that's a problem for smaller SOCs - and what to look for instead.
Read postmTLS in 2026: why certificate-based auth beats tokens
Bearer tokens and API keys are convenient but fundamentally broken for long-running service auth. Here's why mTLS is the stronger choice for endpoint-to-server communications.
Read postHow AI is transforming EDR alert triage in 2026
How large language models are changing EDR alert triage in 2026: automated explanation, incident clustering, and natural language threat hunting for SOC teams.
Read postProcess tree analysis: how SOC teams trace an attack
Learn how SOC analysts use process trees to trace attacker activity from initial foothold to lateral movement, with real examples and detection tips.
Read postAI-powered alert triage: how LightEDR integrates with your preferred LLM
Choose your own LLM: LightEDR's AI triage works with Anthropic, OpenAI, Azure, Gemini, and Ollama to explain alerts and suggest triage steps.
Read postEndpoint isolation: what happens when you click "contain"?
A step-by-step breakdown of what endpoint containment actually does at the network layer, the sequence of events, and when to use it - and when not to.
Read postOur MITRE ATT&CK coverage: what we detect and what we don't
LightEDR maps its behavioural detections to MITRE ATT&CK honestly - here's what we cover well, where the gaps are, and why transparency matters for SOC teams.
Read postWhat is alert fatigue and how does AI help SOC teams?
Alert fatigue is burning out SOC analysts - here's how AI-powered triage reduces noise, prioritises real threats, and keeps your team effective.
Read postZero Trust is not a product - it's an architecture
Zero Trust has become one of the most abused terms in security marketing. Here's what NIST SP 800-207 actually requires, and how to tell the real thing from a rebrand.
Read postHow to evaluate an EDR: 10 questions to ask every vendor
Choosing an EDR is harder than it should be. Here are 10 concrete questions that separate genuine capability from polished marketing decks.
Read postBuilding a SOC on a budget: the case for transparent EDR
Running a SOC on a tight budget doesn't mean compromising on endpoint detection. Here's how transparent EDR pricing changes the maths for lean teams.
Read posteBPF vs kernel modules: why it matters for Linux EDR
How a Linux EDR collects kernel telemetry - eBPF, kernel modules, or plain syscall interfaces - has real consequences for stability, portability, and attacker evasion.
Read post5 things SOC teams hate about legacy EDR platforms
From alert overload to opaque pricing, legacy EDR creates more work than it prevents. Here's what SOC teams complain about - and what to look for instead.
Read postWhat are Sigma rules and why should your SOC use them?
Sigma is the vendor-agnostic detection rule format every SOC team should know. This guide explains the syntax, why it matters, and how to start using it today.
Read postHow much does EDR cost in 2026?
EDR pricing is notoriously opaque. Here's what enterprise and mid-market endpoint detection platforms actually cost in 2026, and what drives the price.
Read postEDR vs XDR vs MDR - what's the difference?
EDR, XDR, and MDR are often used interchangeably in vendor marketing. Here's what each actually means, how they differ, and how to choose the right approach for your team.
Read postWhy we publish our pricing (and why most EDR vendors don't)
Most enterprise EDR platforms hide pricing behind a sales call. Here's why LightEDR publishes every tier openly - and what that means for your budget planning.
Read postMITRE ATT&CK for defenders: which techniques matter most
MITRE ATT&CK catalogues over 400 techniques. Here's how defenders should prioritise coverage - with real detection logic for the techniques that appear most in incident reports.
Read postLightEDR vs CrowdStrike: an honest comparison
A frank look at how LightEDR stacks up against CrowdStrike Falcon for SOC teams that want real detection coverage without enterprise pricing.
Read postWhat is Zero Trust architecture? (NIST SP 800-207 explained)
Zero Trust isn't a product you buy - it's an architecture. We break down NIST SP 800-207, the PDP/PEP model, and what it means for endpoint security.
