Discuss cyber resilience →Senior expertise focused on what the organisation needs to protect and improve.
Practical security and recovery improvements for established organisations, aligned to operational risk rather than generic product bundles. Every engagement begins with the operating context, evidence and a clearly defined outcome.
A practical, accountable service.
Exposure assessment
Identify priority weaknesses across access, endpoints, servers, networks, backups and operating practices.
Resilience controls
Strengthen segmentation, privileged access, monitoring, recovery and ransomware readiness.
Incident preparedness
Clarify escalation, containment, recovery, communications and evidence requirements.
Clear steps. Visible decisions.
Where to start, which is not where most people start
The instinct is to buy something. The more useful first move is to find out what you already have.
In the mid-market environments we assess, a substantial share of the security capability the organisation is paying for has never been configured. Conditional access included in the Microsoft licence and unused. Intune licensed with no devices enrolled. Defender policies at factory defaults. Logging available and not retained. None of that requires a purchase to fix.
The second most common finding is that the controls in place are not the ones that match the actual exposure. Considerable spend on endpoint tooling alongside no multi-factor authentication on administrative accounts, or a next-generation firewall in front of a network where any user can reach any system.
So the order is: find out, fix what you own, then buy only what is genuinely missing. That order is not universally popular with suppliers, and it is the one that produces the most improvement per rand.
The controls that carry the most weight
Not a comprehensive framework. The specific things that, in this market and at this scale, change the position most.
Multi-factor authentication everywhere, without exceptions for administrators
Administrative accounts excluded from MFA because it was inconvenient during a rollout is a finding we make regularly. It is the single most consequential gap.
Legacy authentication closed
Basic authentication bypasses MFA entirely. It persists through old SMTP relay configurations, unattended scripts and line-of-business applications nobody has updated.
Least privilege on identity
Standing global administrator rights held by four people who need them twice a year. Just-in-time elevation is available in most licences already held.
Local administrator rights removed from endpoints
The highest-impact endpoint change available in most environments, covered in detail on endpoint and device management.
Patching with evidence
Covered on patch and vulnerability management.
Network segmentation
A flat network means one compromised endpoint reaches everything. Segmenting servers, users, guests, cameras, building systems and operational technology is architecture rather than product, and it is frequently the largest single structural improvement available.
Email controls
SPF, DKIM and DMARC published, with DMARC moved from monitoring to enforcement on a plan rather than left at p=none indefinitely. Business email compromise is handled at the mailbox and identity layer rather than at the gateway.
Backup that is immutable and tested
The recovery half of resilience, covered on backup and recovery.
Logging that is retained and reviewed
Logs that only exist inside the environment being investigated are of limited value. Retention, and storage the environment cannot delete.
Cyber security in Johannesburg and Gauteng
Most of our security work is with organisations in Johannesburg, the East Rand and Pretoria, and it is delivered remotely with onsite attendance in Gauteng where an assessment or an incident needs it.
Two things come up repeatedly in this market specifically.
POPIA obligations are broader than people assume. Section 19 requires appropriate technical and organisational measures to secure the integrity and confidentiality of personal information, and section 22 requires notification to the Information Regulator and to affected data subjects where there are reasonable grounds to believe personal information has been accessed by an unauthorised person. Having the technical capability to establish what was accessed is what makes that notification accurate rather than a guess, and that capability is logging and retention decided in advance.
Operational technology and building systems. Manufacturing, warehousing and industrial sites in the Gauteng belt commonly have production equipment, building management, access control and cameras on the same network as business systems. Segmenting those is often the highest-value structural work available and it is rarely on the security shopping list.
Penetration testing
Worth being precise about, because it is frequently bought at the wrong time.
What it is
A manual, targeted, time-boxed exercise where a skilled tester attempts to find and chain weaknesses. It finds things scanners cannot: logic flaws, chained privilege escalation, weaknesses in custom applications and gaps between systems that individually look fine.
What it is not
A vulnerability scan. Some suppliers sell an automated scan with a report cover as a penetration test. The distinguishing feature of a real test is a human doing the work and a report describing what they achieved and how, not a list of CVEs.
The types
External infrastructure, internal infrastructure, web application, wireless and social engineering. They answer different questions and they are priced separately. Buying “a penetration test” without specifying which produces a scope argument.
When to buy it
After you have run vulnerability scanning and remediated the findings. Testing an environment that has never been scanned wastes most of the engagement on findings a scan would have given you for a fraction of the cost. Scan first, remediate, then test what remains.
How we work
We scope the test, coordinate an independent testing provider, and then do the part that usually gets dropped: work the findings to closure and verify the fixes. A penetration test report with no remediation programme behind it is an expensive document. The value is in what changes afterwards.
We coordinate rather than perform the testing ourselves, and we say so plainly. There is also a genuine independence argument for the party remediating not being the party testing.
What Namandla delivers
Security assessment
Identity and access, endpoint posture, network exposure and segmentation, email controls, patching and vulnerability position, backup and recovery, logging and retention and cloud configuration. Findings ranked by consequence and by effort, with what you already own separated from what would need buying.
Remediation
The gap-closing work, sequenced so the highest-consequence items move first.
Identity and access hardening
MFA, conditional access, privileged access management, legacy authentication closure, guest and external access review.
Endpoint and email controls
Covered in depth on their own pages and delivered as part of the security programme.
Vulnerability management
Scanning, risk-ranked remediation and exception handling with compensating controls.
Penetration testing coordination, scoping through to verified remediation.
Incident readiness. Response plan, defined roles, communication templates, evidence preservation and the POPIA notification path decided before it is needed rather than during.
Evidence and reporting. Monthly posture reporting written to be usable for customer security questionnaires, insurance applications and audits.
Remote delivery nationally. Onsite in Gauteng.
Common questions about Cyber Security & Resilience
Where should we start with cyber security?
With an assessment of what you already have configured. In most mid-market environments a substantial share of the security capability already licensed has never been switched on, and closing those gaps requires no purchase.
The most common findings are conditional access unused, Intune licensed and not deployed, Defender policies at defaults, administrative accounts excluded from multi-factor authentication and logging available but not retained. Working through those changes the position more than most tooling purchases would, and it costs configuration time rather than licence spend.
How much should we spend on security?
Less than most vendors suggest and differently. The controls that carry the most weight in this market are identity, patching, segmentation, endpoint hardening and tested backup, and most of those are configuration rather than product.
We would rather find that you are already licensed for what you need than sell you something. Where a genuine gap exists we quote it separately and say why. If the assessment finds a well-configured environment, that is what the report will say.
What is the difference between a vulnerability scan and a penetration test?
A scan is automated, broad and frequent, and it identifies known vulnerabilities. A penetration test is manual, targeted and periodic, and it finds what a skilled person could chain together, including logic flaws no scanner detects.
They are complements, and the order matters. Testing an environment that has never been scanned spends most of the engagement on findings a scan would have surfaced for a fraction of the cost. Scan, remediate, then test what remains.
Do you perform penetration testing yourselves?
We scope and coordinate it through independent testing providers, then work the findings to closure and verify the fixes. We do not perform the testing.
That is deliberate as well as honest. There is a real independence argument for the party remediating not being the party testing. The part most often dropped after a test is the remediation programme, and a report without one is an expensive document.
What does POPIA require us to do about security?
Section 19 requires appropriate technical and organisational measures to secure the integrity and confidentiality of personal information. Section 22 requires notification to the Information Regulator and to affected data subjects where there are reasonable grounds to believe personal information has been accessed without authorisation.
The practical consequence is that you need the capability to establish what was accessed, which means logging and retention decided in advance rather than after the fact. Whether your overall processing complies is a question for your information officer, and we give them an accurate description of the technical position to assess.
We have antivirus and a firewall. Is that enough?
They are two controls. The gaps we find most often sit elsewhere: administrative accounts without multi-factor authentication, legacy authentication still permitted, flat networks where one endpoint reaches everything, and backups that have never been restored.
This is not a criticism of either product. It is that the exposure in a modern environment is weighted towards identity and configuration rather than towards perimeter and endpoint alone. An assessment tells you where your specific gaps are rather than which product to add.
How do we handle security for our production or warehouse systems?
Segmentation first. Manufacturing equipment, building management, access control and cameras commonly sit on the same network as business systems, and separating them is usually the highest-value structural work available.
Operational technology often cannot be patched, because the vendor certified a specific configuration. That makes it an exception with compensating controls rather than a remediation target, and the compensating control that works is network isolation. This is common across the Gauteng industrial belt and it is rarely on the security shopping list.
What is incident readiness?
A documented response plan with defined roles and deputies, communication templates drafted in advance, evidence preservation steps and a decided POPIA notification path.
The value is entirely in deciding it beforehand. Working out who has authority, who talks to customers and whether a notification threshold has been met, while an incident is running, produces slow and inconsistent decisions. It takes a day or two to prepare and it is the cheapest resilience work available.
Can you help with a customer security questionnaire?
Yes. Patch compliance, vulnerability remediation, access control, backup and restore evidence, logging and incident readiness all come out of the standing reporting.
These questionnaires are increasingly a condition of doing business with larger customers, and assembling the evidence retrospectively takes days and produces a weaker answer. Where the reporting already exists, answering is largely a transcription exercise.
Do we need a SOC or managed detection?
Sometimes, and it is worth being honest that it is often bought before the basics are in place.
Detection and response adds real value on an environment that already has identity hardened, patching under control, endpoints managed and logging retained. Bought before those, it generates alerts about an environment nobody can remediate quickly, and the cost is significant and recurring. We would rather get the foundations right and then have the conversation about detection with a clear view of what it would add.
When is a full security programme more than you need?
On a small environment with cloud-managed devices, no on-premises servers and no compliance obligation, a hardened Microsoft 365 tenant, managed endpoints and tested backup covers most realistic exposure.
That is genuinely a defensible position at small scale and it costs a fraction of a programme. The case for more grows with on-premises infrastructure, operational technology, regulated data, contractual security obligations or a customer base that audits you. We will tell you which of those apply to you and which do not.
