Cyber Security Services Singapore
The breach that closes a Singapore SME rarely looks like a movie. It looks like an invoice email with one letter changed in the bank account number, clicked by someone having a normal Tuesday. Rezolva provides the cyber security services Singapore small and mid-sized businesses need to make that Tuesday survivable.
We are not a vendor selling you a box. The same engineers securing your perimeter also run the network behind it — so the cyber security services in Singapore you get from us match how your business actually works, not a template.

Managed security services Singapore SMEs can run on a budget
Enterprise-grade security used to require an enterprise headcount. The managed security services Singapore companies get from Rezolva bundle the layers that matter into one monthly arrangement, with humans reviewing what the tools report. Here is that Tuesday again — scroll, and watch every move die.
The invoice email lands. Same supplier name, same signature — one letter changed in the domain, one digit in the account.
Filter log · liveEmail Security
Filtering, spoof-detection and link protection — because one phishing click should cost you an awkward conversation, not the company.
- Spam & phishing filtering
- SPF / DKIM / DMARC spoof protection
- Malicious-link rewriting
- Staff phishing-awareness guidance
A second payload goes to a personal inbox and someone clicks anyway. The dropper starts encrypting a test folder.
Alert triage · SGEndpoint Protection & EDR
Beyond the antivirus Singapore businesses already know: detection and response that spots behaviour, isolates the machine, and tells us before it spreads.
- EDR agent on every endpoint
- Behaviour-based detection & isolation
- Alert triage by an SG engineer
- Monthly threat summary in plain English
Plan B: probe the perimeter for the usual open doors — exposed ports, forgotten rules, a five-year-old ruleset.
Ruleset · reviewedManaged Firewall
The firewall Singapore offices often “set and forget” is configured, patched and reviewed — because a firewall with a five-year-old ruleset is decoration.
- Ruleset review & cleanup
- Firmware patching on schedule
- Change log for every rule
- Quarterly config report you can hand an auditor
Try the remote-access back door instead — the shared VPN login a vendor set up in 2021 and nobody ever rotated.
Encrypted tunnelsBusiness VPN
The VPN Singapore teams need for staff working from home or overseas — so remote access is encrypted and accountable instead of an open back door.
- Per-user access accounts — no shared logins
- Encrypted tunnels for home & overseas staff
- Joiner-leaver account hygiene
- Access logs kept & reviewable
Last resort: the known exploits. CVEs from last quarter that most SMEs still haven't patched.
Patch cycle · on timePatching & Hardening
The unglamorous work that closes the holes attackers actually use, done on schedule.
- OS & application patch cycles
- Server hardening baselines
- Admin-account & password policy review
- Patch report per cycle
Five layers, one monthly arrangement, humans reviewing every alert.
How exposed are you right now?
Flip what you already have in place. The gauge does the maths.
Indicative only — the real answer comes from a gap assessment, not a web page.
Every layer an attacker checks first is unaccounted for. That Tuesday email gets through.
Close the gaps — book the assessmentPenetration testing Singapore — get hacked by us first, on purpose
Defences you have never attacked are defences you are taking on faith. Our VAPT work — vulnerability assessment and penetration testing Singapore regulators, banks and enterprise clients increasingly demand — probes your systems the way a real attacker would, then hands you a prioritised report instead of a ransom note.
Web application penetration testing Singapore
Your customer portal, booking system or e-commerce checkout, attacked methodically: injection, broken authentication, privilege escalation, business-logic abuse. Auditors use the labels interchangeably — this is the website penetration testing Singapore businesses request most.
- OWASP Top 10
- Auth & session flows
- Checkout logic
- Retest ✓
Mobile application penetration testing Singapore
If your business ships an app, it ships an attack surface. Mobile application penetration testing Singapore enterprises commission covers insecure storage, weak API authentication and the data the app leaks when the phone itself is hostile.
- iOS & Android
- Local storage
- API auth
- Hostile-device leakage
Network penetration testing Singapore — external, internal & wireless
The external test asks what an attacker on the internet can reach; the internal test asks what a compromised laptop — or a malicious insider — can do next. Add the wireless penetration testing Singapore offices need when the office Wi-Fi reaches the carpark.
- External perimeter
- Lateral movement
- Wireless & guest
- Segmentation
Cloud penetration testing Singapore
Misconfigured cloud consoles, over-permissive storage buckets and forgotten admin accounts are this decade's unlocked server room. Cloud penetration testing Singapore workloads on AWS, Azure and Google Cloud catches the misconfigurations that scanners score green and attackers score first.
- AWS / Azure / GCP
- IAM & admin accounts
- Storage permissions
- What scanners miss
Choosing a penetration testing company Singapore auditors will accept
The choice comes down to scope and standard: we test to the framework your regulator or client contract names — including the CREST penetration testing Singapore financial institutions commonly specify — and we put scope, methodology and retest in writing before any work begins.
How a Rezolva penetration test runs
Every engagement follows the same four steps, agreed in writing before we start.
Scope
We agree which systems, applications and IP ranges are in play, and which standard governs the test: OWASP, PTES or the annex your regulator names.
Test
A human tester probes the agreed scope; automated scanning supports the work but never replaces it.
Report
Findings arrive severity-ranked with reproduction steps and a plain-English summary your management and your auditor can both read.
Retest
Once the findings are fixed, we verify the fix and issue the closure documentation your compliance reviewer asks for.
What PDPA breaches now expose Singapore companies to. The question regulators ask after an incident is what protection you had in place — and when.
Mapped to PDPA, MAS TRM and PCI DSS — not just “best practice”
Security without a compliance map is effort you cannot prove. We document your controls against the framework that applies to you — so when the auditor or the insurer asks, you answer with evidence, not adjectives.
Penetration testing cost in Singapore — fixed before we start
It scales with scope, and the quote is fixed before any work begins — defined scope, fixed price, severity-ranked report, retest included. One web application is a smaller engagement than an external-plus-internal network test across two offices.
Single application
One web or mobile app — the typical first engagement for an SME.
- OWASP-based scope
- Severity-ranked findings report
- Reproduction steps included
- Retest after you fix
Network engagement
External + internal — the standard scope when an insurer or enterprise client asks for evidence.
- External perimeter test
- Internal lateral-movement test
- Wireless & guest networks included
- One or two offices
- Closure documentation for your auditor
Full VAPT programme
For regulated or audit-heavy industries — scheduled around the strictest framework that applies to you.
- Applications, network & cloud
- Annual retest cycle
- MAS TRM / PCI DSS alignment
- Recurring closure evidence
Defined scope, fixed quote — what you sign is what you pay.
The last layer is a copy they cannot encrypt
No defence is perfect, which is why ours ends with recovery. The ransomware playbook today encrypts your live data and hunts your copies — so we pair every security engagement with protected, restorable backups the attacker cannot reach, and with the physical layer too: the cameras and door access guarding the room your server actually sits in.
One accountable team across all three — the same engineers enterprises like NTU, Prudential and China Telecom have trusted with their infrastructure since 2012.
The room · the copy · the camerasStart with security — add the rest when you're ready
Security never runs alone. Add what you need, when you need it — same Singapore team, one accountable scope, one invoice.
IT Support →
Patching, monitoring and helpdesk are the daily backbone of security — the layer that keeps every other layer current.
Cloud & Backup →
Immutable backup is your last line when prevention fails — the copy the ransomware playbook cannot reach.
Door Access & CCTV →
The cameras and door access guarding the room your server actually sits in — the physical half of the same threat model.
Frequently asked questions
Vulnerability assessment plus penetration testing. The assessment scans broadly for known weaknesses; the penetration test has a human actively exploit what the scan found, proving which weaknesses are theoretical and which are an open door. Most compliance frameworks expect both.
Annually at minimum, plus after any major change — new application, new infrastructure, an acquisition. Card-payment and financial-sector frameworks set their own clocks; we align the schedule to the strictest one that applies to you.
Antivirus matches files against known bad signatures. EDR watches behaviour — a legitimate tool suddenly encrypting hundreds of files gets flagged and isolated even though no “virus” is present. Modern attacks are built to pass the first and get caught by the second.
Smaller firms are targeted precisely because attackers assume thinner defences — and SME attacks are automated, not personal. The phishing kit does not check your headcount before it fires.
It scales with scope: one web application is a smaller engagement than an external-plus-internal network test across two offices. Defined scope, fixed quote, severity-ranked report, retest included — agreed before work starts. See the three scope sheets above.
Yes — enterprise clients increasingly audit their vendors, and we prepare the controls and the documentation that let you answer honestly and win the contract anyway.
