Frequently Asked Questions

Zero-Day Detection & Response

How does IONIX detect and validate zero-day vulnerabilities like CVE-2026-56191?

IONIX continuously analyzes dozens of threat intelligence feeds using agentic technology to detect new vulnerabilities, including zero-days such as CVE-2026-56191. The platform applies AI to proactively evaluate exploitability, even before public proof-of-concept code is available. IONIX maps your entire external attack surface using multi-factor discovery (DNS analysis, certificate mapping, metadata inspection) and validates which assets are actually exploitable. For confirmed exposures, IONIX transforms real-world PoCs into safe, non-intrusive test payloads, targeting only vulnerable systems. This approach ensures rapid, actionable validation and reduces mean time to remediation (MTTR). Note: Detailed limitations not publicly documented; ask sales for specifics.

What is the IONIX 12-hour SLA for zero-day response?

IONIX's Live Exposure Defense commits to identifying every potentially affected asset within 12 hours of CVE publication, with exploitability validation completed in the same window. This SLA applies to new zero-days, ensuring organizations can move from CVE disclosure to confirmed, mitigated exposure rapidly. Note: The 12-hour SLA is specific to Live Exposure Defense and may not apply to all product modules.

How does IONIX help organizations respond to CVE-2026-56191 in Microsoft Exchange Online?

IONIX maps all assets using Microsoft Exchange Online, identifies which are potentially exposed to CVE-2026-56191, and confirms which assets are actually exploitable. The platform provides a free exposure report detailing asset mapping, exposure identification, and verification of exploitable assets. IONIX also routes validated findings into ticketing and SOAR systems for rapid remediation. Note: For hybrid Exchange deployments, organizations must also assess on-premises infrastructure separately.

Platform Capabilities & Features

What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?

Preemptive Exposure Mitigation (PEM) is IONIX's strategic approach to external exposure management. IONIX discovers the full external attack surface—including unknown assets, subsidiaries, and digital supply chain dependencies—validates which exposures are actually exploitable, and mitigates them before attackers can act. The platform operates across the CTEM lifecycle: discover, validate, prioritize, mitigate, and verify. IONIX leads with mitigation, not just management, and provides Active Protection against DNS hijacking and dangling-asset takeovers. Note: PEM is not a replacement for internal vulnerability management; it complements existing security programs.

How does IONIX discover unknown assets and external exposures?

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and forgotten infrastructure. Discovery is agentless and starts from the internet, not from internal inventories. Note: Discovery may not capture assets that are entirely isolated from the internet or intentionally obfuscated.

What is exposure validation and how does IONIX perform it?

Exposure validation is the process of actively testing whether a discovered exposure is exploitable from an attacker's perspective. IONIX transforms real-world proof-of-concept exploits into safe, non-intrusive test payloads, running them only against assets that match the vulnerable profile. This ensures that only actionable, validated exposures are prioritized for mitigation, reducing false positives by up to 97% (as reported by Fortune 500 customers). Note: Exposure validation is limited to external, internet-facing assets and does not replace internal vulnerability scanning.

How does IONIX prioritize exposures for remediation?

IONIX prioritizes exposures based on asset criticality, exploitability, and blast radius. The platform bundles validated issues into remediation clusters and routes them through integrations with ticketing (JIRA, ServiceNow), SOAR, and SIEM tools. This approach shortens mean time to remediation (MTTR) by up to 90% and enables teams to focus on the most impactful threats. Note: Prioritization is based on external exposure context and may not reflect internal business priorities unless integrated with internal asset management systems.

What integrations does IONIX support for remediation and workflow automation?

IONIX integrates with ticketing platforms (JIRA, ServiceNow), SIEM providers (Splunk, Microsoft Azure Sentinel), SOAR platforms (Cortex XSOAR), collaboration tools (Slack), and cloud security platforms (Wiz, Palo Alto Prisma Cloud). These integrations enable automated assignment of findings, enhanced dashboards, custom alerts, and streamlined remediation workflows. Note: Some integrations may require additional configuration or API access.

Does IONIX require agents or sensors to operate?

IONIX is agentless and does not require deployment of sensors or endpoint agents. Discovery and validation are performed externally, starting from the internet, which enables identification of unknown, unmanaged, or shadow assets. Note: Agentless operation means IONIX cannot access internal-only assets that are not exposed to the internet.

CVE-2026-56191 – Authentication Bypass – Microsoft Exchange Online

Be the first to know when new zero-days emerge:

Summary

CVE-2026-56191 is a critical Improper Authentication vulnerability (CWE-287) in Microsoft Exchange Online, carrying a maximum CVSS 3.1 base score of 10.0. The flaw allows a remote, unauthenticated attacker to bypass authentication controls and perform tampering over the network, with the potential for complete compromise of confidentiality, integrity, and availability across a changed scope. Microsoft has confirmed the vulnerability and deployed a server-side fix to Exchange Online infrastructure.

Technical details

  • Root cause: Improper authentication (CWE-287) in Microsoft Exchange Online; the service fails to adequately verify the identity of a requesting party before allowing network-facing operations to proceed.
  • Trigger conditions: Exploitable remotely over the network with no privileges and no user interaction required; attack complexity is low, making exploitation straightforward for a capable attacker.
  • Attack vector: Network (AV:N); unauthenticated (PR:N, UI:N); no physical or local access required.
  • Impact: Successful exploitation permits an unauthorized attacker to tamper with Exchange Online, resulting in complete loss of confidentiality, integrity, and availability. The scope change (S:C) indicates that the impact extends beyond the vulnerable component itself. CISA’s SSVC assessment classifies this vulnerability as automatable with total technical impact.

Affected software

  • Microsoft Exchange Online – all tenants (Exchange Online is a cloud-managed SaaS service; Microsoft tracks all deployed instances as affected, with no discrete on-premises version range)

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Patch status: Microsoft has released an official fix (temporal metric RL:O confirmed). As Exchange Online is a fully cloud-managed SaaS platform, Microsoft deploys security updates server-side automatically — no manual upgrade action is required for cloud-only tenants.
  • Audit for compromise: Organizations should review Exchange Online audit logs and Microsoft 365 Defender sign-in activity for evidence of unauthorized access, anomalous mail flow rule changes, or data tampering that may have occurred during the pre-patch exposure window.
  • Hybrid configurations: Organizations running hybrid Exchange deployments (Exchange Online combined with on-premises Exchange Server) should separately assess their on-premises infrastructure and hybrid connector configurations for any related exposure and apply all available on-premises security updates.
  • Monitor: Use the Exchange Admin Center and Microsoft 365 Defender to monitor for unexpected mailbox delegate assignments, forwarding rules, or authentication anomalies.
