Penetration testing

Penetration testing services

See every threat. Prevent every risk to business continuity. Automated scans catch typos, not attack paths. Our penetration testing consultants chain small flaws into real breach scenarios. We're ISO 27001 certified and test both complex enterprise platforms and startup solutions under NDA.

How can penetration testing protect your business?

Identify vulnerabilities that automated scans miss

Scanners flag known issues and stop there. Our team chains "low-risk" gaps into one working breach path. That's exactly how a real attacker would find your data.

Understand your real-world security exposure

A firewall report doesn't show what a live attack looks like. Our infrastructure penetration testing maps how an intruder actually moves through your network. You see the true blast radius, not a theoretical score.

Validate your security controls

Owning security tools isn't the same as knowing they work. We run application penetration testing against your live environment, not a staging copy. You find out if your defenses hold before an attacker tests them for you.

Support security and compliance requirements

PCI DSS, HIPAA, and ISO 27001 all expect documented, regular testing. Our penetration testing as a service model keeps that evidence current year-round. Auditors get a paper trail; you get one less compliance scramble.

Our penetration testing services

Application pentesting

Web and mobile apps hide logic flaws that scanners never catch. Our mobile app penetration testing services test both the interface and the API behind it. For Shiji, we secured a wide product portfolio spanning multiple hospitality platforms. Every product page, login flow, and data field got checked before launch.

External network pentesting

Your public-facing systems are the first thing attackers probe. External penetration testing simulates that exact approach against your DNS, firewalls, and web servers. We map what's visible from outside, then try to break through it. You see your exposure the way a real intruder would.

Internal network pentesting

A breach rarely stops at the front door. Internal penetration testing shows what happens once someone's already inside your network. On projects like SyncMatix, we worked across multi-tenant systems handling live data from hundreds of connected devices. That kind of architecture taught us how lateral movement actually spreads.

Cloud pentesting

Cloud misconfigurations open doors nobody notices until it's too late. Our cloud penetration testing checks IAM policies, storage permissions, and service boundaries directly. We've built and secured AWS-hosted platforms handling real-time fleet and telematics data. That production experience shapes how we test yours.

Hardware pentesting

Connected devices carry their own attack surface, separate from your software. We test IoT sensors, GPS units, and embedded systems for weak points. Physical access, firmware flaws, and communication protocols all get evaluated. If it connects to your network, it's in scope.

AI / LLM pentesting

AI systems introduce failure modes traditional testing was never built to catch. Our AI penetration testing probes prompt injection, data leakage, and model manipulation directly. We've built production AI platforms like DriveIQ, so we know where these systems actually break. That build experience is exactly what makes our AI testing sharper.

Our six-step pentesting process

We start by defining exactly what's in play, not guessing at boundaries mid-test. That means confirming target systems, testing windows, and rules of engagement upfront. A website penetration testing project needs different scoping than an internal network sweep. You get a signed-off scope before a single tool runs.

Deliverable: scope document, rules of engagement, testing schedule.

Attackers gather intelligence fast, and so do we. Our team maps your public footprint, open ports, subdomains, and exposed services. For AWS penetration testing services, for instance, that means enumerating S3 buckets, IAM roles, and misconfigured security groups before touching anything live. This phase builds the map everything else runs on.

Deliverable: asset inventory, attack surface map.

Automated scans flag the obvious; our engineers chase what scanners miss. We combine tooling with manual review across every layer in scope. Our vulnerability and penetration testing services blend both approaches deliberately, since scans alone leave logic flaws untouched. You get a ranked list, not a raw dump of alerts.

Deliverable: vulnerability findings log, initial risk ratings.

Finding a flaw isn't the same as proving it matters. We chain weaknesses together the way a real attacker would, carefully and under control. For API penetration testing services at this stage, we test broken auth, injection points, and rate-limit bypasses directly against live endpoints. Every exploit attempt stays scoped, logged, and reversible.

Deliverable: proof-of-concept exploits, exploitation log.

A finding nobody understands doesn't get fixed. We write reports your engineers and your auditors can both use. Each issue gets severity, business impact, and a clear reproduction path. No jargon dump, no forty-page filler nobody reads twice.

Deliverable: full technical report, executive summary.

Testing without a fix is just a list of open doors. We work alongside your team while they patch, then retest every closed item. This final pass confirms the fix holds, not just that a ticket got marked done. You walk away with verified, working defenses, not a hope they'll work.

Deliverable: retest report, closure confirmation, compliance-ready documentation.

Which security testing methodologies do we use?

OWASP

This framework anchors our application penetration testing services, covering the top web and API risks. It keeps injection, auth, and logic flaws front and center.

PTES

The Penetration Testing Execution Standard structures full engagements end to end. We lean on it for cloud penetration testing services, where scope spans dozens of interconnected services.

OSSTMM

This open-source model measures security operationally, not just technically. It's useful for network engagements where trust boundaries matter as much as code.

NIST

Federal-grade guidance shapes our approach to regulated environments and compliance-driven audits. Clients in finance and healthcare lean on this one the hardest.

CREST

This accreditation standard governs how we run mobile penetration testing, especially for apps handling payment or health data. It sets a bar for consistency across every tester on the team.

Six reasons to trust our penetration testing services

Twenty years inside one demanding vertical

Booking engines, payment forms, and supplier integrations don't forgive sloppy security work. We've built and secured travel, logistics, and mobility platforms for almost two decades. Our mobile application penetration testing services draw on apps we've shipped ourselves, not just audited from outside.

We test what we've built, not just what we're told

Reading documentation only gets a tester so far. Our engineers have built the exact systems they now test: booking flows, marketplaces, and fleet platforms. That production background shapes how we run application penetration testing services, since we know where shortcuts hide.

Engineers who stay, context that compounds

Median engineering tenure at COAX runs 6.5 years, well above industry norms. The tester who ran your last engagement still knows your architecture. Our internal penetration testing services benefit most from that continuity, since lateral-movement risk depends on institutional memory.

Certified, audited, and NDA'd every time

We hold ISO 9001 and ISO 27001 certification company-wide, not as a marketing badge. Every engagement starts under NDA, before we touch a single credential. That discipline applies to a one-week scan and a six-week engagement alike.

Built for complex, connected stacks

Modern platforms rarely run on one clean system. They connect payment gateways, telematics feeds, and third-party APIs into one surface. Our web penetration testing services account for that complexity, since we've built the middleware connecting these systems ourselves.

Reports two audiences can actually use

A finding nobody understands doesn't get fixed. We deliver executive summaries for leadership and full technical evidence for engineers. Both come from one engagement, so nobody's translating findings into a second format later.

FAQ

Pricing depends on scope, not headcount. A single external network test can run far cheaper than a full application review with exploitation. Most first engagements land in the low-to-mid five figures, scaled by attack surface. We scope before quoting, so founders see cost tied to actual risk, not a flat rate pulled from a price list.

App store reviews check for obvious policy violations, not exploitable flaws. This testing goes deeper, examining API calls behind the interface, local data storage, and session handling on the device itself. We've caught insecure token storage that passed every store review without issue. Passing Apple or Google's checklist confirms baseline compliance, not real security against a determined, motivated attacker. 

Yes, external testing targets what's already internet-facing, so it rarely touches production stability directly. We schedule intensive phases like exploitation during low-traffic windows and keep a rollback plan ready regardless. Downtime risk comes from live database changes, not simple probing. Founders worried about uptime should flag critical release dates during scoping, before testing windows are set.

Not necessarily. We can start from a simulated compromised laptop, a guest network, or actual VPN credentials, depending on what threat you're modeling. Remote and hybrid teams usually need the VPN scenario tested, since that's the real entry point attackers target now. The access model gets picked with you during scoping, matched to how your team actually works day-to-day.

We stop and notify you immediately, before continuing any planned testing. Every engagement includes an emergency contact clause for exactly this scenario. It's rare, but not unheard of, especially in unpatched cloud environments. Testing pauses until your team confirms the incident is contained, then resumes under a revised scope. Founders should never treat this clause as boilerplate; it matters.

SOC 2 questionnaires confirm that policies exist; they don't prove your code holds up under a real attack. This kind of testing checks actual endpoints, auth flows, and input handling live, not paperwork. Auditors accept both, but only one shows evidence of real resilience. We've seen companies pass SOC 2 with vulnerabilities a first-day pentest would catch immediately. Compliance and security aren't the same thing.

Usually, yes, since most diligence checklists ask for evidence of testing against your live application. Term sheets increasingly include a security review clause, and scrambling after signing looks worse than planning. Startups that book testing early get a clean report to hand over, not a rushed scramble under deadline pressure. We've supported founders through exactly that timeline crunch before.
