Continuous Monitoring: 24/7 Attack Surface Surveillance

Your attack surface is never static. Every day, new subdomains appear, credentials surface in breach databases, lookalike domains get registered by threat actors, and shadow IT slips past your internal controls. Continuous monitoring means you know the moment something changes — not weeks later during a quarterly review, but immediately, with full context and a clear path to remediation.

​

What Gets Monitored

Leverage Cyber watches every layer of your external digital footprint around the clock.

​

Monitoring Cadence

Continuous monitoring operates across three distinct layers, each designed to give the right information to the right people at the right time. 1. Real-Time Alerts When a high-severity or critical exposure is detected, you receive an immediate notification — no waiting for a scheduled report. Real-time alerts are reserved for findings where attacker dwell time directly translates to increased risk, such as leaked executive credentials or an actively exploitable subdomain takeover opportunity. See Alerts and Notifications for full details on delivery channels and severity thresholds. 2. Daily Digest Every morning, you receive a summary of all new findings discovered since the previous digest. The daily digest consolidates medium- and low-severity changes into a single, scannable report so your security team can triage efficiently without being overwhelmed by individual notifications. Each finding in the digest includes its ALE impact and recommended next action. 3. Quarterly Reassessment Each quarter, Leverage Cyber reruns the full initial assessment against your organization and produces a trend report comparing your current risk posture to the prior period. The quarterly reassessment captures structural changes to your attack surface — newly acquired subsidiaries, domain portfolio shifts, technology stack changes — that continuous feed monitoring alone may not fully surface. See Quarterly Reassessment for a complete breakdown.

How Monitoring Works

All monitoring is entirely passive. Leverage Cyber never sends a packet to your infrastructure, never triggers a WAF rule, and never causes service disruption. The intelligence pipeline draws from the following sources:

• Continuous OSINT feeds — aggregated public intelligence sources covering new asset registrations, certificate issuance, and technology fingerprinting across the open web
• Breach database synchronization — real-time ingestion from credential breach repositories, paste sites, and dark web markets where leaked data is traded and published
• DNS monitoring — ongoing resolution tracking for your known domain portfolio, detecting changes to records, new subdomain registrations, and dangling DNS entries that create takeover risk
• Certificate transparency log watching — every TLS certificate issued for a domain associated with your organization is captured within minutes of issuance, surfacing unauthorized subdomains and lookalike infrastructure
• Dark web feed monitoring — structured and unstructured dark web sources are continuously monitored for mentions of your organization, your domains, and your key personnel

Because the entire methodology is passive reconnaissance, there is nothing for your IT or network team to accommodate or allow-list.

What Triggers an Immediate Alert

Not every finding warrants waking someone up. Immediate alerts are reserved for exposures where delay materially increases your risk:

• C-suite or privileged account credentials leaked — credentials for executives, domain administrators, or any account with elevated access are treated as critical regardless of the system they belong to
• Subdomain takeover risk detected — a dangling DNS record pointing to an unclaimed cloud resource that an attacker can claim and weaponize against your users
• New critical CVE affecting a discovered technology — when a zero-day or critical vulnerability is published and Leverage Cyber has already identified that technology in your external footprint, you receive an immediate alert correlating the CVE to your specific exposed assets
• Newly registered lookalike domain — a domain registered within the past 24–48 hours that closely resembles your primary domain, indicating active preparation for a phishing or brand-impersonation campaign
