Firewalls, segmentation, exposure and access rules
This is a short sub-page for the network layer. Firewalls, segmentation, exposed services and access rules are tested for exploitable gaps, with retesting after fixes. US product and security teams get this work in US hours, 9am to 1pm Eastern, with delivery from India, under ISO/IEC 27001. Scope is the agreed in-scope assets. We do not claim certified security staff. A free external attack-surface check of one domain is the first look from the outside.
Network penetration testing
We simulate real-world attacks against the agreed in-scope network to identify and exploit vulnerabilities, inside written limits. This is the network slice, not a full product VAPT. That full engagement sits on penetration testing.
Wi-Fi security testing
We assess the security of the agreed in-scope wireless network so sensitive data is protected and unauthorised access is prevented. The dedicated wireless method sits on wireless security testing. This page names the layer. That page is the longer pass.
Firewall and intrusion detection testing
We evaluate the effectiveness of your firewall and intrusion detection systems so unauthorised access is blocked and security events are detected early. A finding looks like a temporary rule that became permanent, or an admin path that should not be reachable from the internet.
Need segmentation and exposure tested, not another application scan? Book a scoping call, or start with a free external attack-surface check of one domain.

The overview that routes the rest of the set is security testing. Hosts, cloud IAM and configuration sit on infrastructure security testing. Stay here when the problem is firewalls, segmentation, exposed services and access rules on the agreed in-scope network. Every engagement ends with a retest of those assets.
Stay on this page
The problem is the network: segmentation that does not hold, firewall rules that drifted, wireless that was supposed to be guest-only, and services that answer on the internet. You want those agreed in-scope assets tested, a risk-ranked report, and a retest.
Go to penetration testing
You need an authorised attacker across the application, API, mobile and infrastructure. Penetration testing is that method. We do not run both as two invoices for the same week unless you asked for both.
Proof from delivery
Sector only. The anonymous bank numbers, then four further engagements. They are security delivery, not a claim that each was a network-only job.
Anonymous bank · VAPT and audit evidence
Before: vulnerability noise was burying the work that mattered, fixes took over 40 days, and audit preparation took five days. After: 68% less vulnerability noise, time to fix under 16 days, audit preparation from 5 days to 5 hours, and a 3.5 times high-risk closure rate.

SaaS gamingFrequently Asked Questions
Price follows the agreed in-scope set: how many segments, firewalls, exposed services and access rules, whether exploitation is in, and that a retest is part of the work. We quote after that list is written down. We do not publish a day-rate on this page. This URL is network and segmentation, not a full VAPT. A free external attack-surface check of one domain is the first look from the outside.
Application, API, mobile, network, infrastructure, wireless and a full penetration test. This URL is network security testing and segmentation review: firewalls, segmentation, exposed services and access rules. The overview that routes the rest is security testing. VAPT across the product sits on penetration testing. Infrastructure hosts sit on infrastructure security testing. Wireless sits on wireless security testing. Pick the layer you actually have.
Unauthorised testing is illegal. Authorised testing of agreed in-scope assets, with written permission, is the engagement. We do not scan a neighbour you did not name. This page is network and segmentation. A full authorised attacker across applications sits on penetration testing. Book a scoping call before anyone touches a host. The rules of engagement are written down first. We do not claim certified security staff.
We will not invent a ranked five. This URL is network and segmentation, not a tool catalogue. A scanner dump with no owner is not the engagement. Judge a vendor on agreed in-scope, manual verification and a retest after fixes. Tools named on the infrastructure page stay there. Book a scoping call if the question is which check you are buying, not which logo. The free external attack-surface check of one domain is how we see the outside first.
A penetration test is quoted after the agreed in-scope product is written down: applications, APIs, mobile and infrastructure. That work sits on penetration testing, not on this page. This URL is network and segmentation. Price follows segments, exposure and whether exploitation is in. We do not publish a project total here. A free external attack-surface check of one domain is the first look. Book a scoping call for the network slice.
Judge a vendor on written permission, agreed in-scope, a retest after fixes, and whether they will say this page is network rather than a full VAPT. Ranked lists are not that. Vervali is an ISO/IEC 17025 accredited lab with CMMI Level 3 process, US-hours coverage and delivery from India. We do not rank ten firms. Penetration testing is the VAPT page. This page is the network sub-page.
No. AI can widen a scan. A person still confirms a finding is real, stays inside agreed in-scope, and retests the fix. This page is network and segmentation. A scanner dump is not a pentest. We do not claim certified security staff. The report is risk-ranked with a path to harm. Book a scoping call if you want that confirmation, not a bot-generated PDF. The retest after fixes is part of the original work.
It is an authorised test of a web application for exploitable gaps, with a retest after fixes. That method sits on penetration testing. This URL is network security testing and segmentation review: firewalls, segmentation, exposed services and access rules. The overview is security testing. We will not pretend a network pass is a web app pentest. Book a scoping call for the layer you actually have. Pick one problem, then one page.
