Manual, adversary-driven external penetration testing and internal penetration testing that models how a real attacker would breach and pivot through your environment. Evidence-grade VAPT reports in 15 business days.
Free Assessment
Infrastructure penetration testing is a manual, adversary-simulating engagement where our CREST and OSCP certified testers use the same tradecraft as real attackers to breach your perimeter, establish foothold, escalate privilege, move laterally, and reach your crown-jewel assets. The goal is not to list vulnerabilities, it is to prove business impact.
External pen testing targets your internet-facing surface: web servers, VPN endpoints, email gateways, cloud load balancers, public APIs, DNS, and exposed management interfaces. We look for chained exploitation paths that turn a medium-severity finding into initial access.
Internal penetration testing starts with the assumption of breach. Our tester is given a plugged-in workstation or a low-privilege VPN account. From there we model real-world lateral movement: kerberoasting, AD CS abuse, LLMNR poisoning, print-nightmare, SCCM takeover, BloodHound path analysis, and credential relay against your domain.
Every engagement produces a business-impact narrative, a finding-by-finding technical appendix, a lateral-path graph, and a compliance mapping for ISO 27001, SOC 2, PCI DSS, HIPAA, and DPDP. You get a named lead tester, Slack or Teams access during the engagement, and a free retest to prove remediation.
Perimeter exploitation from the internet: public APIs, VPN, email, cloud edges.
External penetration testingAssumed-breach scenario inside the LAN, AD, and server VLANs.
Internal penetration testingWe chain low and medium findings into high-impact exploitation paths.
Real adversary pathsEvery action is logged, reversible, and confined to pre-agreed targets.
Consent-scoped exploitationScreenshots, exploit videos, and lateral-path graphs for every finding.
Proof, not listsA clean VAPT report opens doors with enterprise procurement, lowers cyber insurance premiums, and shortens the audit cycle. Skip it, and every single one of those costs compounds.
Pick the right test for your audit, buyer, or insurance deadline. Or run both in a single engagement for a 20 percent package discount.
Our recommendation: Our recommendation: Run external annually and internal biannually. Customers on this cadence experience a 70 percent drop in critical findings year-over-year and close ransomware-grade paths before an adversary finds them.

Answers to the questions buyers ask us most often during a infrastructure penetration testing evaluation: scope, pricing, methodology, tools, safety, reporting, retesting, and compliance mapping.
Our lead testers can walk you through scope, pricing, SLAs, methodology, and compliance mapping in a 30-minute no-pressure call.
A vulnerability assessment enumerates and validates weaknesses. Infrastructure penetration testing takes those weaknesses and chains them into exploitation paths, proving what an attacker could achieve inside your environment. Most regulations require both, and ISpectra delivers both in a single bundled engagement.
If you have never tested, run external penetration testing first to prove your perimeter story. Then run internal penetration testing to prove your assumed-breach story. Most customers run external annually and internal biannually after the first full cycle. Both produce evidence that auditors, insurers, and boards require.
External pen testing takes two to three weeks for a mid-sized attack surface. Internal penetration testing takes three to four weeks. Full external-plus-internal engagements typically close in six weeks. Retests are delivered within 10 business days of your remediation window closing.
We follow PTES, OSSTMM, and CREST-aligned external network penetration testing methodology. Phases are reconnaissance, enumeration, vulnerability identification, exploitation, post-exploitation, and reporting. Every engagement is documented against this methodology so auditors can inspect our testing rigor.
Our testers use Burp Suite Professional, Nmap, Nuclei, Metasploit, Impacket, BloodHound, NetExec, Responder, Cobalt Strike under licensed engagements, and proprietary ISpectra tooling. Tool selection is driven by the test narrative, not a vendor checklist.
No. We operate under consent-scoped rules of engagement, respect blackout windows, throttle noisy checks, and use safe-exploit profiles. Over 400 engagements we have never caused a reportable service incident.
Yes. Infrastructure penetration testing is explicitly required by SOC 2 CC7.4, ISO 27001 A.8.29, PCI DSS 11.4, and HIPAA Security Rule 164.308(a)(1)(ii)(A). Our report is written to satisfy each of these plus DPDP Act reasonable security safeguards and RBI and SEBI cyber resilience frameworks.
Executive narrative, business-impact statement, kill-chain diagrams, technical appendix with reproduction steps, CVSS 3.1 scores, compliance mapping, blue-team detection rules, retest results, and a co-branded VAPT certificate.
Yes. Every engagement includes one free retest cycle. We retest every high and critical finding, update severity to reflect remediation, and reissue the VAPT certificate. Additional retests are priced at a discounted subscription rate.
External pen testing starts at USD 6,500 for a modest perimeter. Internal penetration testing starts at USD 9,500. Full annual retainers covering both price from USD 24,000 and include quarterly surface monitoring, a free retest, and priority incident response.
