WHY MANAGING YOUR ATTACK SURFACE IS HARDER THAN EVER
EXTERNAL PERIMETERS KEEP EXPANDING
New cloud services, abandoned subdomains, and legacy services expand your attack surface faster than you can secure it.
ATTACK SURFACES ARE CONSTANTLY CHANGING
Reconfigurations, updates, and expired certificates can create new vulnerabilities between your point-in-time scans.
LOW VISIBILITY INTO DIGITAL ASSETS
Traditional, siloed security tools fragment your view, hiding critical exposures across your infrastructure and shadow IT.
SECURITY TEAMS ARE OVERWHELMED BY ALERTS
Analysts waste hours triaging thousands of alerts without knowing which vulnerabilities are genuinely exploitable.
Continuous Asset Discovery
ASM maps your entire digital footprint automatically. By combining DNS enumeration with advanced crawling, it finds all internet-exposed assets—including forgotten subdomains and shadow IT—to ensure you have full visibility of your external attack surface.
Active Vulnerability Verification
Active testing verifies real vulnerabilities, not just theoretical ones. Using dynamic analysis (DAST) and safe-exploit simulation, ASM confirms whether known CVEs or potential weaknesses, like SQL injection and exposed admin panels, are actually exploitable.
Risk-Based Prioritization
NordStellar cuts through the noise by prioritizing vulnerabilities based on verified exploitability rather than theoretical severity. It separates false positives from genuine threats, giving you a clear view of which issues pose an immediate danger to your organization.
Remediation Support
Turn insights into action with a prioritized remediation queue. NordStellar ASM provides detailed evidence and fix guidance for every verified vulnerability, enabling your security team to close critical gaps immediately before they can be exploited.
SIX WAYS NORDSTELLAR STRENGTHENS ATTACK SURFACE MANAGEMENT
Instantly see every external asset
Continuous discovery eliminates shadow IT blind spots, ensuring forgotten subdomains and abandoned services never become attacker entry points.
Stop chasing false positives
Active exploit validation verifies which vulnerabilities are genuinely exploitable, so your team stops wasting time on theoretical risks and focuses on real threats.
Catch what human error leaves behind
Automated detection finds any unpatched CVEs, exposed admin panels, default credentials, and expiring certificates so you can fix them before attackers exploit them.
Cut down analyst triage time
Risk-based prioritization replaces overwhelming alert queues with a verified hit-list, directing limited resources to validated, exploitable vulnerabilities first.
Adapt monitoring to suit your needs
Set scheduled scans at times that work for your team, or run on-demand scans when you need fresh data for incident response, audits, or post-deployment validation.
Remediate faster with clear guidance
Detailed fix instructions and exploit evidence for every validated vulnerability eliminate research time, enabling your team to close critical gaps quickly.
WHAT NORDSTELLAR DETECTS ACROSS YOUR ATTACK SURFACE
From Shadow IT to Web Vulnerabilities, NordStellar uncovers 6 key risk vectors.
Exposed admin panels
Locate publicly accessible login portals, specifically those using weak or default credentials like admin/admin.
Subdomain takeovers
Identify forgotten subdomains that attackers could hijack to host malicious content and impersonate your brand.
Gaps in DNS and email security
Flag missing email authentication (SPF, DMARC) that leaves your domain vulnerable to spoofing and phishing.

NordStellar lets your cybersecurity team patch critical vulnerabilities and intervene at the earliest stages of an attack – before any real damage is done.
Dark web monitoring
Dark web monitoring allows you to track all keywords associated with your business across deep and dark web communities, such as hacker forums, illicit marketplaces, and Telegram channels. It helps you uncover brand mentions, issues with vendors, and leaked information about your VIP personnel.
Data breach monitoring
Data breach monitoring involves scanning the deep and dark web for leaked sensitive information linked to your business. To spot breached data, NordStellar checks infostealer malware logs, leaked databases, and collections of stolen credentials combinations. This solution provides real-time monitoring and the full context of past and present attacks.
Cybersquatting detection
Cybersquatting detection helps you recognize and prevent threat actors from impersonating your brand. Using content and visual similarity algorithms enriched with AI, NordStellar can detect various domain manipulations and issue real-time alerts, providing a detailed view of each suspicious domain.
Frequently asked questions
An attack surface is every possible entry point an attacker could use to gain access to your systems. It includes your internet-facing web apps, network services, employee accounts, and any other digital asset that can be targeted. Keeping this surface as small as possible is key to reducing your security risk.
Attack Surface Management (ASM) is the continuous process of discovering, monitoring, and securing all of your company's internet-facing assets. The goal is to find and fix exposures on those assets before attackers can exploit them.
NordStellar goes beyond simple discovery by actively simulating attacks against your digital footprint. This verifies which vulnerabilities are genuine, exploitable threats, so you can focus on fixing what actually matters.
You can't protect what you can't see. Your digital footprint is always expanding with legacy assets, shadow IT, and new cloud services, creating unknown security gaps. ASM gives you a complete and current map of all your external assets so you can find gaps and close them before they lead to a breach.
NordStellar uses the same techniques attackers do. It combines DNS enumeration, subdomain brute-forcing, and advanced web crawling with OSINT analysis to build a complete map of your digital footprint. This process identifies every internet-facing asset tied to your organization, from web apps and IP addresses to forgotten cloud services, giving you a true attacker's-eye view.
NordStellar detects a wide range of high-impact security risks, including:
- Verified web vulnerabilities like SQL injection, XSS, and RCE
- Exposed admin interfaces, especially those with default or weak credentials
- Subdomain takeover opportunities on forgotten assets
- Sensitive data leaks from public configuration files or backups
- Unsecured network services and open ports like SSH, FTP, or RDP
- Known vulnerabilities (CVEs) in your exposed software
- DNS and email security gaps, such as missing SPF or DMARC records
Yes, NordStellar ASM covers any public-facing cloud assets that are part of your external attack surface. This includes cloud-hosted web applications, publicly accessible storage buckets, and any other services you have exposed to the internet. However, it does not scan internal cloud configurations or private infrastructure behind your firewall.
Compliance with privacy laws such as GDPR and HIPAA often depends on proper data storage and protection procedures. As ASM aims to close gaps in your security, it can greatly contribute to compliance with regional privacy laws as well as global standards and regulations like ISO 27001, NIS2, and DORA.
Choosing the best attack surface management solution comes down to evaluating your company’s specific needs. Consider the size of your infrastructure, the sensitivity of your data, and the complexity of your external assets.
Ultimately, ASM is a continuous process, so it’s important to find a reputable company you can collaborate with for years to come. One such company is NordStellar. As part of Nord Security, NordStellar offers years of cybersecurity expertise, modern tools for proactive threat detection, and advanced attack surface monitoring.
