# Casdomain

*/Startups/Casdomain*

## Startup Overview

This API-native platform continuously audits DNS configurations to prevent subdomain takeovers. It maps an organization's external digital footprint, scanning for dangling DNS records and misconfigured routing rules that expose orphaned subdomains to hijacking. By integrating directly into cloud providers and DNS management tools, it monitors record changes in real time.

Security and infrastructure teams manage sprawling web ecosystems where temporary campaigns, deprecated cloud services, and forgotten deployments leave behind vulnerable entries. Instead of relying on manual audits that leave windows of exposure, administrators use this continuous monitoring engine to detect hijacking risks the moment a backend resource is de-provisioned but its DNS record remains active.

Legacy domain management platforms like Cloudflare Secure Registrar or MarkMonitor focus on registrar-level security, leaving operations teams to rely on periodic, script-driven DNS reviews. This solution replaces static point-in-time checks with an automated, continuous monitoring layer, directly bridging the gap between cloud resource lifecycle management and strict DNS configuration control.

## Startup Founding Hypothesis

## Startup Offer

**Proof**:
- Targets zero manual DNS auditing cycles per quarter for DevOps teams.
- Aims to detect unmapped CNAME records within five minutes of an underlying cloud resource deletion.
- Designed to evaluate 50,000+ DNS records continuously without rate-limiting underlying cloud providers.
**Tiers**:
- Name: Standard Monitoring · Price: ~$99–$150/mo · Inclusions: Continuous auditing for up to 5 DNS zones, daily deep-scans for dangling records, and standard email alerting for infrastructure teams.
- Name: Advanced Protection · Price: ~$300–$600/mo · Inclusions: Auditing for up to 50 DNS zones, continuous API-driven monitoring, and intended webhook integrations for automated incident routing.
- Name: Enterprise Complete · Price: ~$15k–$25k/yr · Inclusions: Unlimited zone monitoring, sub-minute vulnerability detection polling, and designed to integrate directly with SIEM providers and enterprise SSO.
**Guarantee**: If Casdomain fails to generate an alert for a dangling DNS record that results in a confirmed subdomain takeover, we will refund your trailing 12 months of service.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: We already use a managed DNS provider like Cloudflare. Rebuttal: Managed providers route your traffic securely but do not monitor the external lifecycle of the cloud buckets or services your records point to.
- Objection: We cannot grant third-party tools write-access to our DNS. Rebuttal: The platform requires strictly read-only API tokens scoped specifically to DNS configuration endpoints.
- Objection: Will this bury our team in alerts for normal DNS updates? Rebuttal: The system filters alerts specifically for confirmable takeover conditions, such as a CNAME pointing to an unregistered third-party service.

## Startup Buyer Chain

**Chain**: Casdomain → DevSecOps Engineer → Enterprise Attack Surface
**Gtm Motion**: Acquires users through a self-serve, single-domain audit that instantly flags dangling DNS records and vulnerable CNAMEs. Expands by converting these single-scan users to ongoing, API-native continuous monitoring subscriptions covering all organizational root domains.
**Agent Channel**: Intends to publish an OpenAPI specification to the tool registries of autonomous security frameworks, enabling AI-driven red-team agents and security posture managers to autonomously discover and provision continuous DNS monitoring.
**Primary Channel**: Developer security newsletters (such as tl;dr sec) and organic search, capturing infrastructure engineers actively querying for 'automated subdomain takeover prevention' or 'dangling DNS scanner'.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 14-day shadow pilot monitoring up to 50 DNS zones to identify at least one pre-existing dangling record vulnerability without disrupting current routing
- A 30-day enterprise proof-of-concept integrating SIEM to validate sub-minute vulnerability detection polling across a high-volume multi-cloud architecture
**Target Metrics**:
- Target: < 5 minutes to detect an unmapped CNAME record after an underlying cloud resource deletion
- Aim: 0 manual DNS auditing cycles required per quarter for infrastructure teams
- Target: 100% of alerts strictly tied to confirmable takeover conditions to eliminate false positives
- Aim: 50,000+ DNS records evaluated continuously via read-only APIs without provider rate-limiting
**Target Case Studies**:
- A mid-sized fintech DevOps team transitioning from manual quarterly DNS audits to continuous, automated dangling record detection
- An enterprise e-commerce security director securing 50,000+ DNS records across multiple cloud environments without rate-limiting their provider
- A SaaS infrastructure lead eliminating alert fatigue by replacing noisy manual scripts with validated subdomain takeover vulnerability alerts
**Testimonial Targets**:
- VP of Security expressing relief that external cloud resource lifecycles are monitored without requiring write-access to their core DNS
- DevOps Engineer highlighting the complete elimination of manual dangling record deep-scans from their routine maintenance sprints
- Chief Information Security Officer validating the operational confidence provided by the 12-month refund guarantee against undetected subdomain takeovers

## Startup Top Risks

**Risks**:
- Severity: existential · Description: Major DNS providers like Cloudflare or AWS Route53 release free, built-in continuous subdomain takeover prevention features that eliminate the need for a standalone tool. · Mitigation Status: unmitigated
- Severity: high · Description: API rate limit enforcement or breaking changes from major registrars block the continuous monitoring pipeline and cause critical blind spots. · Mitigation Status: in-progress
- Severity: high · Description: Enterprise security teams refuse to grant the broad IAM permissions required to connect the continuous monitoring API, stalling deployments. · Mitigation Status: in-progress
- Severity: moderate · Description: A high volume of false positives triggered by intentionally parked but inactive subdomains causes alert fatigue and eventual customer churn. · Mitigation Status: unmitigated

## Startup Story Brand

**Hero**:
- **Need**: to be the infrastructure architect who builds resilient systems, not a vulnerability firefighter
- **Want**: to prevent subdomain takeovers without performing periodic manual DNS audits
- **Identity**: the security engineer at a cloud-native enterprise
**Plan**:
- Step: Select · Detail: Choose the DNS zones in Cloudflare or AWS Route 53 that require continuous protection.
- Step: Audit · Detail: Let our engine deep-scan your entire infrastructure for vulnerable CNAME and A records.
- Step: Secure · Detail: Receive real-time alerts or webhook triggers the moment a resource deletion creates a takeover risk.
**Guide**:
- **Empathy**: You shouldn't still be manually checking zone files. Cloudflare Secure Registrar wasn't built to monitor the lifecycle of the underlying resources your records point to.
**Problem**:
- **Villain**: dangling CNAME records
- **External**: stale DNS entries in Cloudflare point to deleted AWS S3 buckets or Azure services that attackers can hijack
- **Internal**: you feel exposed knowing a major security breach is one forgotten record away
- **Philosophical**: Every security engineer deserves automated visibility — not a list of manual audit tasks.
**Success**: Your DNS zones remain clean and secure, with every dangling record identified and remediated before an attacker finds it.
**One Liner**: Instead of relying on manual DNS audits, Casdomain continuously monitors your zones for dangling records — preventing subdomain takeovers before they happen.
**Positioning**:
- **So That**: eliminate subdomain takeover risks via real-time infrastructure lifecycle monitoring
- **Unlike**: manual DNS audits
- **For Whom**: security engineers at cloud-native enterprises
- **Category**: Continuous DNS Security Platform
**Call To Action**:
- **Direct**: Start continuous audit
- **Transitional**: View sample vulnerability report
**Failure Stakes**:
- Subdomain hijacking leading to data breaches
- Damage to brand reputation from hosted phishing sites
- Wasted DevOps hours on manual DNS cleanup
**Transformation**:
- **To**: securing infrastructure via continuous API-driven monitoring instead of manual audit cycles
- **From**: a DevOps engineer hunting stale records in spreadsheets
**Controlling Idea**: DNS security should be an automated continuous process, not a manual checklist.
