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. As the cyber security company Singapore businesses keep on retainer, Rezolva builds the five layers that decide whether that Tuesday becomes a payment, a breach, or a logged non-event.

We are not a vendor selling you a box. The same engineers securing your perimeter also run the network behind it, the office CCTV and door access systems on top of it, and the web hosting and Microsoft 365 and business email your staff rely on — so the cyber security services in Singapore you get from us match how your business actually works, not a template.

Cyber Security Services Singapore : five layers, one Tuesday

Enterprise-grade security used to require an enterprise headcount. The cyber security company Singapore SMEs can actually afford bundles 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.

Email security filtering managed by Rezolva engineersFilter log · live
Layer 01 · Email Security

Email 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.

Layer 02 · Endpoints

Endpoint 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.

Managed firewall infrastructure reviewed quarterlyRuleset · reviewed
Layer 03 · Perimeter

Managed 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.

Network security monitored by RezolvaEncrypted tunnels
Layer 04 · Remote access

Business 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.

Patching & Hardening

The unglamorous work that closes the holes attackers actually use, done on schedule.

  • Server hardening baselines
  • Admin-account & password policy review
  • Patch report per cycle

How exposed are you right now?

Flip what you already have in place. The gauge does the maths.

Is your firewall ruleset reviewed at least quarterly?no
Do all endpoints run EDR — not just antivirus?no
Is your email protected against spoofing (SPF / DKIM / DMARC)?no
Does every remote user have their own VPN login?no
Were servers and apps patched in the last 30 days?no
Has a human penetration-tested you in the last 12 months?no

Indicative only — the real answer comes from a gap assessment, not a web page.

The layer that fails first

Cybersecurity Training Singapore — the layer that fails first

Four of the five layers are technical, and the attacker knows it. The cybersecurity training Singapore staff actually remember is not an annual slide deck — it is a simulated invoice email in their real inbox on a real Tuesday, followed by a payment rule that does not depend on anyone feeling suspicious.

0/4 ARMED
Untrained

The technical layers are bought once. This one is the only layer an attacker can talk to - and the only one that decays if nobody keeps it current. Arm the modules you actually run.

Why the training layer sits inside the retainer, not beside it

Most cyber security companies Singapore SMEs meet sell the training as a separate certificate. Training that is bought once decays in a quarter. Inside a retainer it becomes a measured control: simulation results feed the risk register, the register drives the roadmap, and the roadmap is what the board signs off. That loop is the difference between a certificate and a lower click rate.

How it works

CISO as a Service — how the engagement runs

A fractional CISO is a few days a month, not a headcount. The engagement runs on the same four steps every time, agreed in writing before we start, so you always know what lands and when.

opened
01

Baseline

Two days looking at what you actually run: mailboxes, endpoints, cloud tenancy, who has admin, what leaves the building. You get the gap list before anyone proposes anything to buy.

Risks ranked by what they would cost this business, each with a named owner and a date, and a twelve-month sequence of controls with budget attached.

Scope and days per month agreed with the client before a CISO engagement starts

Scope and days per month are agreed before anything starts. The register and the roadmap are the deliverables — reviewed monthly, not written once and filed.

PDPC · Financial penalty ceilingSG
S$1,000,000
— or, if higher —
10% of annual SG turnover

What PDPA breaches now expose Singapore companies to. The question regulators ask after an incident is what protection you had in place — and when.

Compliance

Cyber security services Singapore, 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.

PDPAFor everyone holding personal data in Singapore.
MAS TRMFor financial services and their vendors.
PCI DSSFor anyone touching card payments.
Cyber EssentialsThe CSA baseline mark, for SMEs still building the basics.
Cyber TrustThe CSA risk-based mark larger buyers and regulated clients ask for.
Pricing

CISO as a Service Pricing — what actually moves the number

CISO as a service pricing scales with three things: how many systems are in scope, how often you need us on site, and whether a certification or a client contract sets the clock. The quote is fixed before any work begins — no hourly drift.

If everything above fails

Singapore cyber security company — 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.

The Rezolva Singapore security team

One accountable team across all three — the same engineers enterprises like NTU, Prudential and China Telecom have trusted with their infrastructure since 2012.

Frequently asked questions

The cyber security services Singapore SMEs actually need come in this order: harden email and identity, train the people who receive the email, put detection on the endpoints, write down who decides what, and prove the lot with testing and a recoverable backup. Most SME breaches are stopped by the first two, which is exactly where thin security budgets tend to spend last.

It is a fractional security leader — a few days a month rather than a hire. Search cybersecurity Singapore and you get government portals and job ads; what an SME needs is a named person who owns the risk register. You need one when someone has to own the risk register, answer customer security questionnaires and stand in front of the board, and nobody in the company currently has that in their job description.

Filters stop the mass campaigns. The email that costs money is the targeted one that reads like a real supplier — it passes the filter and lands on a person. Training plus a payment-verification rule is what stops that email becoming a transfer.

Yes — every Singapore organisation must appoint a DPO, and we hold that role as a service. That includes the data inventory, the policy that matches what you really do, and the notification clock: notifiable incidents must reach the PDPC within 3 calendar days.

Cyber Essentials suits organisations still building the basics and is valid for two years; Cyber Trust is the risk-based mark with five tiers, a three-year validity and an annual surveillance audit, and it is what larger buyers and regulated clients tend to ask for. We start with what your customer contract actually names.

We scope and run it, delivered under a CSRO licence, with a severity-ranked report, reproduction steps and a retest after you fix. One scope, one accountable party — you do not manage two vendors pointing at each other.

There is a named incident commander, a decision list written before the incident rather than during it, and monitoring that isolates a device instead of logging a warning. The record that comes out of that night is what your insurer and, if it is notifiable, the regulator will read.

By scope, fixed before work begins. Cyber security services Singapore SMEs buy are priced on how many systems are in play, how often you need us on site, and whether a certification or client contract sets a deadline — not on hours logged after the fact.
