Penetration Testing for Charleston Businesses
Find out whether the controls you already pay for hold up under a real attempt, and get findings specific enough to hand to whoever fixes them.
What a penetration test is
A penetration test is a person working inside an agreed scope to get further into your systems than the design intends. A scanner lists what might be wrong; a test establishes what actually is, by doing it. What comes back is a set of findings with the evidence attached.
The four kinds, and what each one looks at
External and internal network
From outside, what is reachable from the internet and what it gives away. From inside, how far someone starting on an ordinary workstation or a guest connection can get from there.
Cloud configuration review
The tenant and subscription settings themselves: identity and access rules, what is published to the internet, and permissions that are broader than the job they were granted for.
Web application and API
Authentication and session handling, access control between one account and another’s data, injection, and the business logic that only comes apart when the steps are taken out of order.
Phishing and social engineering
A controlled campaign against your own staff, measured on what gets clicked and what gets reported, so awareness training is aimed at what actually happened rather than at a generic script.
Test, fix, verify, then watch
-
A score is not a simulation
A configuration score tells you a control is switched on. It does not tell you whether it holds. Switching on conditional access and establishing that it actually stops movement between systems are different pieces of work, and usually only the first one has been done.
-
The fix is part of the job
A report that arrives and then sits somewhere has changed nothing. Every finding comes with remediation written for the environment it was found in, and the work of closing it is available from the same people who found it.
-
Confirmed closed, in writing
Remediated findings are retested and the closure is written down. The engagement finishes when the holes are shut, not when the document is delivered.
-
Then it stays watched
Microsoft Defender and Microsoft Sentinel already run here as a monitoring practice in Azure. What a test changes goes into the same timeline, so the next round is aimed by what has actually moved in the estate rather than by a date in the calendar.
Three things happen, in this order
Scope it
What is in bounds, how much the tester is told in advance, and when testing runs. That last pair change what the test is able to find, so they are settled deliberately rather than assumed.
Test it
The work itself, inside the agreed window. Findings are confirmed by hand rather than passed through from a tool’s output, and chained wherever two small things add up to one real route.
Fix it and prove it
Remediation, a retest of each finding, and written confirmation of what is now closed.
What separates a test from a scan
-
A scanner lists, a test establishes
Automated scanning matches known signatures against a target and reports everything that might apply, and a share of that is always wrong. A test takes those candidates and works out which are real by attempting them. That is why a test returns fewer findings than a scan and why they are worth more.
-
Two small findings can be one large one
A scanner rates each finding on its own. A tester looks for the route: a low-severity disclosure plus a second low-severity misconfiguration can combine into something neither is separately. That route is the finding, and it is the one no tool reports.
-
Evidence attached to every finding
A finding is written up with what was done and what came back, not as an assertion that something is possible. That is what lets a single item be handed to a developer who can then reproduce it without a meeting.
-
A summary somebody without a security background can act on
The report opens with what matters in plain language and what to do first, ahead of the technical detail. A document that starts at the technical detail is not read by the person who authorises the fix.
-
How much the tester is told changes the result
Black-box starts from nothing, grey-box starts from an ordinary low-privilege account, and white-box adds architecture and source. Each finds a different set of things. Choosing between them is a scoping decision rather than a level of service.
-
Retesting is the part that is usually missing
Confirming a remediated finding is genuinely closed takes a second pass against the same target. Where that pass is absent, what a business actually holds is a list of things somebody intended to fix.
Who this is built for
Firms with a date to meet
Where a test is something you are asked to produce evidence of on a schedule, and the date is already known.
Firms that have just changed something
A migration, a new application, another office, or a cloud tenant that has grown by accretion. The estate is not what it was when anyone last looked at it.
Firms already paying for the controls
Where identity rules, endpoint protection and conditional access are all switched on, and what they stop has not been established.
Questions
A scan is automated and lists what might be wrong, including things that turn out not to be. A test is performed by a person who confirms which of those are real, looks for routes that combine several of them, and provides the evidence for each one.
No. A test is a normal way to start, and plenty of engagements begin there and go no further until there is something to fix.
If you take card payments, yes – annually, and again after significant changes to the infrastructure in scope. Other frameworks treat it as supporting evidence rather than naming it outright, which is covered in <a href=”/ai/compliance-review/”>compliance and quality pre-review</a>.
That is what scoping settles. It depends on what you run, what changed recently, and whether anyone is asking you for a particular one.
A report that opens with a plain-language summary, then each finding with its severity, the evidence for it, and remediation written for your environment. After the fixes, written confirmation of what retested clean.
It can be. The findings come with remediation guidance either way, and the work of applying it is available from the same people rather than handed to somebody else to interpret.
