Penetration Testing Nebraska
Penetration testing
for Nebraska businesses.
NEBIS tests the way an operator would: agree the bounds, take the path that is actually there, prove what it reached, and close it.
External network, internal network, web application, and cloud identity. If the question is whether anyone would notice a patient adversary, that is a red team engagement. This page shows how far a skilled attacker can get inside the scope you set.
Start a Penetration Test →Who tests
The people who test you
passed a real exam.
Our penetration testers hold OSCP — Offensive Security Certified Professional. Candidates compromise live machines in a timed exam and write up the path, or they fail.
That is the bar we put on this work. You are buying operators who had to break into systems under pressure before they were allowed to do it on yours.
The test
A penetration test proves a path.
Penetration testing is an authorized attack against a scope you approve. The output is evidence: what was reached, how, and which fix closes that path.
Nebraska firms buy this when an insurer, a customer, or a board asks for proof. Ongoing protection lives with cybersecurity services. This engagement answers a specific question, on a defined date, against systems you name.
What's included
What the engagement covers.
- Written scope and rules of engagement before any testing starts
- External and internal network penetration testing
- Web application and API testing against the apps you actually run
- Microsoft 365, Entra ID, and cloud identity testing
- Evidence, reproduction notes, and a ranked remediation plan
- Retest of the paths that actually opened
- OSCP-holding testers who passed a hands-on exam
What we test
Scope the surface.
Then attack that.
A penetration test is only as honest as its scope. These are the engagements NEBIS runs for Nebraska businesses. We will tell you which one matches the question you are trying to answer before anyone quotes it.
External network penetration testing
This is the view from the internet: public IPs, VPNs, firewalls, remote-access portals, and the services that should stay unreachable. We map what an outsider can see, then try the paths that are actually there and write down what those paths reach.
Internal network penetration testing
Most damage happens after someone is already on the network. An internal test starts from a position you agree — a user laptop, a guest segment, a compromised account — and shows how far that foothold reaches. Flat networks, shared admin credentials, and unpatched servers are the usual reasons a small foothold becomes the file server.
Web application penetration testing
Customer portals, vendor apps, and the internal tools your team built get tested as applications. We look at authentication, access control, session handling, and the inputs an attacker would abuse. If the app talks to an API, the API is in scope too. Business-logic flaws count when we can prove them.
Cloud and identity testing
Nebraska firms run Microsoft 365, and many also run Azure, AWS, or Google Cloud. Identity is often the real perimeter: a mailbox, a legacy protocol, an over-permissioned admin role. We test the tenant and cloud accounts you put in scope and report what a stolen password, or a mis-set sharing link, would actually reach.
Retest and remediation support
The engagement continues after the report lands. We rank fixes by how an attacker would chain them, stay available while your team or ours closes them, and retest the items that opened a path.
How it works
Align. Attack.
Prove. Harden.
Four stages, in that order. Nothing is touched before the rules of engagement are signed, and nothing is called a finding unless we can show the impact.
Align
Scope, identities, assets, and constraints get written down before anyone touches a system. You know what is in bounds, what is off limits, and what a successful test is supposed to prove.
Attack
We pursue real paths: weak identity, exposed services, chained misconfigurations. We follow each lead through to impact. The work stops at the boundary you set.
Prove
Each finding includes what we reached, how, and why it matters to the business, with evidence and reproduction notes. We prioritize the findings we can prove.
Harden
We rank what to fix first by how an attacker would use it, then stay with you through remediation. We retest the items that actually opened a path so the environment is harder when the engagement ends.
Which test
Pick the question
before you pick the test.
Firms get sold the expensive name for the cheap deliverable. The difference is the question you are paying to answer.
How far can someone get?
Penetration test
A skilled operator, inside a written scope, proves impact and writes down the path. External, internal, web application, or cloud — picked to match the question you need answered.
Would anyone notice?
Red team engagement
A red team engagement assumes someone is already trying and scores whether your people and detection notice and stop the objective. That work has its own page.
If detection is the point, start with red team engagements. If the board wants the ways in, stay on this page.
Who it's for
When a Nebraska business
actually needs this.
A penetration test earns its place when something specific has to be proven. A customer security questionnaire. A cyber insurance renewal that asks whether you test. A new customer portal. A flat internal network nobody has looked at since the last server refresh. An internal IT person who wants a second set of eyes before they spend the remediation budget.
Day-to-day security still has to run the other fifty weeks. Patching, identity, backup, and monitoring live with cybersecurity. If you already have internal IT, co-managed IT carries that work alongside your team. Findings that belong in an insurance or audit file also feed risk management.
You do not have to move the rest of your IT to NEBIS to buy a test. If we already run the environment through managed IT, scoping is faster because the asset list is not a discovery project. Either way, the rules of engagement are the same.
Where we test
Omaha-based.
Nebraska in scope.
NEBIS is at 8998 L St, Omaha. Penetration testing for Omaha and Lincoln businesses is the core of this work, and the same engagement covers Bellevue, Papillion, La Vista, Fremont, Grand Island, and Council Bluffs across the river.
Most testing is remote, against systems you authorize in writing. On-site work covers wireless, a wiring closet, and hardware that is not on the internet. Every market we cover gets the same rules of engagement.

Common questions.
What is a penetration test?
A penetration test is an authorized attempt to break into an agreed set of systems the way an attacker would, then prove what that access reaches. NEBIS writes the scope first, tests only what is in bounds, and reports evidence and a ranked fix list.
What types of penetration testing do you offer in Nebraska?
External network, internal network, web application and API, and cloud and identity testing against Microsoft 365, Azure, AWS, and Google Cloud. Scope is written before any testing starts, including what is off limits.
Do you penetration test Omaha and Lincoln businesses, or only remote?
Both. NEBIS is based in Omaha and serves Lincoln, Bellevue, Papillion, La Vista, Fremont, Grand Island, and Council Bluffs, Iowa. Most of a penetration test is remote against systems you authorize. When the scope includes on-site wireless, a server room, or hardware that is not reachable remotely, we are in the state.
Who performs the penetration test?
Our penetration testers hold OSCP, Offensive Security Certified Professional. Candidates compromise live machines under a time limit and write up the path, or they fail.
Is a penetration test the same as a red team engagement?
A penetration test shows how far a skilled operator can get inside a scope you set. A red team engagement tests whether your people and detection would notice and stop an objective-driven attack. If the question is whether anyone would notice, that work lives on the red team page.
How much does a penetration test cost?
It depends on the surface: external, internal, web applications, cloud identity, and whether you want a retest. We scope it against your actual environment and quote the engagement before work starts.
Will a penetration test disrupt our systems?
Rules of engagement name production systems, testing windows, and anything that must stay untouched. Testing stays inside that boundary. You get a named contact for the duration of the test, and we respond within 1 business day when you are scheduling it.
