Endpoint security is no longer just antivirus installed on laptops. A resilient program has to connect device, identity, cloud and administration activity; detect and contain attacks; and prove that critical systems can be restored. The trends documented in 2024 point toward that continuous, identity-aware operating model—not toward relying on an AI feature or a single security product.
Why endpoint security now extends beyond the device
Endpoints remain a common place for attacks to begin or become visible, but the activity around them often crosses other systems. A stolen password can expose cloud services; a legitimate remote-management tool can be misused to control a workstation; and an endpoint alert may make sense only when correlated with identity or email events.
Microsoft reported more than 600 million cybercriminal and nation-state attacks against its customers each day in 2024. CrowdStrike’s 2024 Threat Hunting Report recorded a 70% increase in the use of remote monitoring and management (RMM) tools to execute endpoint attacks. These are different measures from different organizations, not a single estimate of endpoint incidents. Together, they illustrate why a device-only view can miss important attack paths.
Antivirus still has a role: it can block known malicious files and other threats. But a signature-focused antivirus view by itself is not enough to investigate suspicious behavior, connect events across services, or contain a compromised identity. Endpoint protection is best treated as a coordinated set of controls, with an endpoint agent as one part of it.

EDR and XDR: what is the difference?
Endpoint detection and response (EDR) monitors activity on endpoints, detects suspicious behavior and provides investigation and response actions. Extended detection and response (XDR) correlates security signals across multiple domains, such as endpoints, identity, email, cloud and network systems. Product boundaries vary: one vendor’s XDR may rely on its own services, while another may integrate with third-party tools.
| Capability | EDR | XDR |
|---|---|---|
| Primary view | Endpoint activity and endpoint alerts | Correlated activity across connected security domains |
| Typical value | Investigating and responding to suspicious behavior on a device | Connecting related events—for example, an account compromise followed by endpoint activity |
| What to verify before buying | Device coverage, detection quality, isolation options, investigation context and administration overhead | Which sources it can ingest, how well it correlates them, what response actions it can take, and whether the team can handle the resulting alerts |
XDR is not automatically better for every organization. If an organization lacks the integrations or staff to act on cross-domain alerts, a well-operated EDR deployment may be more useful than a broader platform that generates uninvestigated findings. Compare products by their actual telemetry sources, response permissions, integrations and effect on analyst workload—not by the label alone.
The endpoint-security trends shaping the next phase
AI-assisted attacks and AI-supported detection
AI is a dual-use capability. Gartner’s 2024 Hype Cycle for Endpoint and Workspace Security said generative AI can enable more advanced cyberattacks as well as threat detection. It highlighted issues including AI-enhanced phishing, QR-code phishing (sometimes called quishing), threat-based vulnerability management, XDR and unified endpoint security.
For defenders, automation can help sort alerts, correlate events or suggest remediation. Those capabilities do not establish that a product can prevent every AI-assisted attack. Ask vendors what data informs a detection, how analysts can verify it, what an automated action is allowed to do, and how the system records who or what approved that action. Start with bounded automation and human approval for high-impact steps such as disabling accounts or isolating critical servers.
Identity-aware endpoint defense
A device can be healthy while the account using it has been stolen. Microsoft reported in 2024 that password-based attacks accounted for over 99% of the 600 million daily identity attacks it described. CrowdStrike’s 2024 threat reporting also emphasized stolen credentials in attacks exploiting cloud gaps. These figures describe the organizations’ reported attack activity; they are not a universal rate for every company.
Pair endpoint controls with phishing-resistant multifactor authentication (MFA), conditional access, least privilege and device-posture checks. Make sure responders can rapidly revoke sessions or credentials as well as isolate a device. Otherwise, containing one laptop may leave an attacker’s active account or other sessions untouched.
Rank #3
Ransomware defense measured by containment and recovery
Microsoft reported a 2.75-fold year-over-year increase in human-operated ransomware-linked encounters in 2024, while also reporting that the proportion of organizations reaching encryption had fallen by more than threefold over the preceding two years. The first figure concerns encounters; the second concerns how often attacks reached encryption. They are not contradictory: more encounters can coexist with fewer attacks reaching that stage.
Prevention and early containment matter, but the outcome also depends on whether the organization can restore operations. CISA’s StopRansomware Guide recommends measures including cloud backups, zero-trust architecture, privileged-account safeguards and user awareness and training. Treat tested restoration, segmentation and offline or immutable backup copies as parts of endpoint resilience. A backup is not a recovery capability until the organization has demonstrated that it can restore the needed systems and data.

Abuse of legitimate administration tools
RMM software lets IT teams manage devices remotely, so its presence is not inherently suspicious. CrowdStrike’s 2024 report of increased RMM-tool use in endpoint attacks makes visibility and context important: organizations should know which tools are approved, where they are installed, and who is authorized to use them.
Rank #4
When evaluating EDR or XDR, check whether it can inventory approved RMM tools, flag unusual use, show process relationships (including parent and child processes), and support prompt isolation. Plan how isolation will affect legitimate remote administration so a response does not inadvertently remove the team’s means of managing a device.
Zero trust, SSE and SASE
Zero trust is an architecture and operating model, not a single appliance or product purchase. It calls for ongoing verification of users, devices, workloads and the specific resources they request. For endpoints, that means access decisions should take account of identity and device posture rather than assuming a device is trustworthy because it is on a corporate network.
In June 2024, CISA urged organizations to move toward Zero Trust, Secure Service Edge (SSE) and Secure Access Service Edge (SASE) to improve visibility into network activity. In December 2024, NIST’s draft SP 1800-35 described 19 sample zero-trust implementations developed with 24 vendors. Those examples show that zero trust can be implemented through different combinations of capabilities; they are not a requirement to buy a particular vendor’s stack.
Governance and supply-chain visibility
NIST Cybersecurity Framework (CSF) 2.0, published on February 26, 2024, applies to organizations of any size, sector or maturity and places added emphasis on governance and supply-chain risk. NIST SP 1302, finalized on October 21, 2024, explains how CSF Tiers describe the rigor of an organization’s risk-governance practices and can help track improvement.
Use the framework to define the outcomes the organization needs before selecting tools: what devices and identities are in scope, who owns each control, what evidence will show that it works, and how often it will be reviewed. NIST describes CSF 2.0 as guidance for industry, government agencies and other organizations to manage cybersecurity risks. A framework profile can guide a purchase without tying the organization to one security vendor.

Compare the capabilities the team can operate, not just feature counts. Ask vendors to demonstrate relevant workflows with the organization’s devices and existing identity, email, cloud and network services. Record what is included in the proposed license and what requires another product or service.
| Selection area | Questions to ask |
|---|---|
| Coverage | Which laptops, servers, mobile devices, virtual machines and cloud workloads are supported? Can the platform use identity context as well as endpoint telemetry? |
| Prevention and detection | How does it combine signatures, behavior monitoring, exploit protection, attack-surface reduction and threat hunting? What investigation context accompanies an alert? |
| Response | Can responders isolate a device, roll back changes or initiate credential actions? Which actions can be automated, which require approval, and where is the audit trail? |
| Telemetry and interoperability | Which SIEM/SOAR, identity-provider, email, cloud and network integrations are available? Are they included, and what data or actions can pass through each integration? |
| Operations | How are deployment, policy tuning and false-positive handling managed? Does the organization have the staffing to operate it, or is a managed service needed? |
| Resilience and governance | How does the product support recovery workflows, least privilege and supply-chain visibility? Can it provide evidence for the organization’s chosen CSF outcomes? |
| Commercial fit | Are licensing, data residency, renewal terms and migration effort clear for the organization’s locations and deployment model? |
What a small business should protect first
A small business does not need to begin by purchasing the broadest platform available. Start with the controls that close common paths into business accounts and make incidents containable. If there is no dedicated security team, account for the time and expertise needed to monitor alerts; a tool that nobody can operate is not a practical protection plan.
- Inventory what must be protected. List laptops, servers, cloud workloads, user and administrator accounts, and approved remote-management tools. Identify who owns each item and remove devices or accounts that are no longer needed.
- Set a risk baseline and target. Use NIST CSF 2.0 to describe the current state, the outcomes the business needs, assigned owners and evidence of progress. Choose a level of governance appropriate to the organization’s risk and maturity rather than treating a tier as a product certification.
- Secure accounts and access. Require phishing-resistant MFA where available, apply conditional access and least privilege, and establish a process for quickly revoking credentials and sessions.
- Deploy and tune EDR. Cover the devices that handle business data. Configure tamper protection, isolation and relevant exploit controls; tune alerts and confirm that approved RMM tools are visible.
- Add cross-domain correlation when it is operable. Connect identity, email, cloud and network signals through XDR or a SIEM when the team can triage and respond to them. Define who receives alerts and who is authorized to take disruptive actions.
- Prove recovery works. Maintain offline or immutable backups as appropriate, segment critical systems, and test restoration. Document incident communications and decision-making, not just the backup schedule.
- Review quarterly. Revisit AI-related detections and automation safeguards, vendor and supply-chain risks, alert handling and progress against the target profile. Adjust policies when the evidence shows they are not working as intended.
How to tell whether the program is improving
Count outcomes that indicate whether the controls work, not just how many alerts or licenses exist. Set a baseline, assign an owner to each measure and review trends on a defined cadence. Useful measures include:
- Share of in-scope endpoints inventoried and actively reporting to the security platform.
- Coverage of phishing-resistant MFA and least-privilege controls for accounts that can reach business-critical resources.
- Time from a high-confidence detection to triage, containment and credential revocation, measured separately.
- Time required to restore a representative critical system in a recovery exercise, and whether the restored data meets business needs.
- Share of approved RMM tools inventoried, with anomalous use reviewed and resolved.
- Alert volume requiring human review, false-positive patterns and the backlog of unresolved high-risk findings.
- Progress from the organization’s current CSF profile toward its target outcomes, with evidence and named owners.
These measures should reflect the organization’s environment and risk. A falling alert count alone, for example, does not prove that attacks are being stopped; it could also mean a data source stopped reporting. Validate the underlying coverage when interpreting a metric.
