External pentesting

Do you have a complete view of your organisation's true cybersecurity risk profile?

NodeZero helps you proactively find, fix, and verify exploitable attack paths resulting from weak credentials, misconfigurations, and vulnerabilities. Run external pentests to assess your assets and digital risk at the perimeter. See your organisation through the eyes of an attacker.

01

Discover, authorise, pentest, repeat

Find and fix internal and external attack vectors before they can be exploited — on-premises, in the cloud, or a hybrid of both. With a combined view of external and internal pentests, you'll understand your complete cyber risk profile across your entire environment.

Proof an attacker reached it, not a claim that they could

NodeZero shows you the exact attack vectors that lead to a critical impact, so you know precisely what to fix to disrupt the kill chain. Every weakness carries timestamped proof of exploitation — the evidence that NodeZero reached and compromised the asset, not a theoretical severity score. That is exactly the artefact an ISM vulnerability assessment or Essential Eight patch-application review needs to show a weakness existed and was closed.

NodeZero proof of exploitation: timestamped evidence of a compromised credential used to access the domain
Timestamped proof of exploitation: the evidence NodeZero actually exploited the weakness and what it reached — the audit artefact a point-in-time scan can never produce.
03

Continuously verify fixes and catch new exposure

Don't just rely on a point-in-time pentest. Run NodeZero continuously and compare results across reassessment cycles to see exactly what new weaknesses have appeared and which fixes have held. When you remediate, NodeZero confirms the weakness has moved to verified — the continuous-improvement evidence an IRAP reassessment or DISP membership expects, not a once-a-year snapshot.

NodeZero remediation verified: a fixed weakness confirmed mitigated on re-test
Remediation verified: NodeZero re-tests each fix and confirms closure, so reassessment shows a trend you can defend rather than a single moment in time.

Why run external pentests with NodeZero

External pentesting finds your organisation's footprint on the internet, using tools and methods an attacker would.

01

Verify ransomware exposure

Understand what attack paths ransomware actors can exploit to breach the perimeter, move laterally within the network, and gain access to crown jewel data.

02

Visualise the risk and impact

See the risk and impact of misconfigured third-party applications and weak or default credentials as an attacker would use them to breach your perimeter.

03

Improve asset management

Continuously discover public-facing assets, hybrid cloud assets, and internal assets.

04

Understand third-party and supply chain risks

NodeZero can be run continuously, both internally and externally, providing an immediate understanding of third-party and supply chain risks. For SOCI-regulated operators, it gives evidence for the supply-chain hazards a CIRMP must address by testing the external perimeter of supplier interconnects and cloud-hosted systems; for DISP members, it supports the supply-chain assurance expected of defence-industry suppliers.

05

Save time and resources

Penetration tests can be set up within minutes and executed as often as needed. No extensive tuning, training, or certifications are required, and results are prioritised with proof, so time and resources can be spent fixing only what matters.

06

Continuous security assessments

Run autonomous penetration tests as often as needed so blue and red teams can complement each other's efforts.

How it works

Continuous external assessment

NodeZero maps your organisation's internet-facing footprint using the same methods attackers would.

1

Discover

NodeZero's Asset Discovery is a passive enumeration capability that leverages DNS and other open-source intelligence (OSINT) gathering capabilities and services to find all of the assets linked to your organisation.

2

Authorise

NodeZero gives you the information you need to understand where your assets are hosted and what third-party services they are linked to. You have fine-grained control over how you group your assets and which ones you authorise to pentest.

3

Pentest

NodeZero is every organisation's purple team partner, orchestrating hundreds of attack tools and techniques across your entire environment to chain attack paths and demonstrate real risk and impact — the offensive half of the loop, so your blue team can focus on detection and response.

4

Proof

NodeZero helps you understand the attack vectors that lead to a critical impact, so you know exactly what to fix in order to disrupt the kill chain — with the evidence artefacts an ISM vulnerability assessment or Essential Eight patch-application review needs to show the weakness existed and was closed.

5

Continuous

Don't just rely on a point-in-time pentest. Continuously assess your security posture, and quickly compare NodeZero results across reassessment cycles to see what new weaknesses have appeared or been fixed — the continuous-improvement evidence IRAP reassessment and DISP membership expect, not a once-a-year snapshot.
