Frequently Asked Questions

How can security construction budget immediately achieve positive ROI?

We use ransomware expected loss model: Expected Loss = Annual Revenue × 1.5% × 7.8% industry probability. Reduce this value to <¥100,000 to cover service fees, ROI > 200%.

Can OT isolation be done with 0 hardware?

Use existing firewalls + VLANs + whitelists to block 99% of lateral movement, 0 new devices, deployed in 17 factories.

1. We spend so much on security construction, what actual value can it bring? Can it prevent hacker attacks?

Answer: The core value of security construction is to change “high probability of being compromised” to “low probability of being compromised and quickly detected”, and reduce “post-compromise loss” from tens of millions to under one hundred thousand. No enterprise globally can promise to prevent all attacks (including Google, Microsoft), but through systematic construction, successful intrusion probability can be reduced by over 90%, average detection time (DWELL TIME) can be shortened from industry average 183 days to hours, and business interruption loss can be reduced by over 95%. This has been an ROI verified by numerous ransomware incidents globally.

2. We are a traditional enterprise/SME, do we really need to spend millions on MLPS Level 3?

Answer: MLPS Level 3 is not “needs to spend millions”, but “if something happens, it could cost tens of millions”. According to Cybersecurity Law Articles 21, 59, 66, critical information infrastructure operators failing to implement Level 3 protection requirements can be fined ¥500,000-1 million and ordered to suspend business for rectification, responsible persons can be held criminally liable. In 2024, multiple hospitals and manufacturing companies were fined + network suspension for 7-30 days due to ransomware, with direct economic losses far exceeding construction costs.

3. There are so many security companies, how do we judge if you’re just a “PPT company”?

Answer: Look at three points:

1. Whether you have real large-scale red-blue team exercise cases (can provide sanitized battle reports);
2. Whether core team comes from first-tier vendors like Palo Alto Networks, Fortinet, CrowdStrike, Rapid7, Check Point, Cisco, etc., or from security departments or national teams;
3. Whether you’re willing to do a 2-4 week real attack test (red team assessment) first, only provide results without charge, then discuss construction plans. This “inspect before pay” model can truly distinguish capabilities.

4. We had a company do MLPS before, passed the assessment, why were we still hit by ransomware last year?

Answer: Passing MLPS assessment ≠ having real security capabilities. 80% of MLPS projects are “document security” not “technical security”, only meeting compliance requirements (patches, policies, documents), but not solving core problems: unclear assets, unpatched vulnerabilities, no lateral blocking, lack of detection and response capabilities. Ransomware loves targets that are “compliant but incapable”.

5. Zero trust sounds hot, should we adopt it?

Answer: Zero trust is not a product, but an architectural concept. Traditional enterprises should currently focus on “micro-segmentation + continuous identity verification” two minimum viable capabilities, rather than directly buying a vendor’s zero trust suite. Suggest solving first:

• Can core databases be directly accessed by operations staff?
• Can jump servers prevent full-network lateral movement after credential theft? If the answers to these questions are “no”, then zero trust is essential, with higher priority than WAF, firewall upgrades.

6. Where should security construction start?

Answer: Strict priority order (proven applicable to 80% of enterprises): Step 1: Asset inventory (know what you have) → Step 2: Vulnerability management (know where holes are) → Step 3: Baseline checks + micro-segmentation (minimize hole impact) → Step 4: Establish detection and response capabilities (EDR+XDR+SOC). Those who do Step 4 first are just paying tuition.

7. We deployed some domestic firewall in our internal network, why were we still compromised?

Answer: Firewalls protect “external-to-internal”, modern attacks 90% are “internal-to-internal” lateral movement. Attack chain is usually: phishing email → workstation compromise → domain controller credential theft → lateral movement → core system encryption. Firewalls are completely blind after Step 2. Must supplement micro-segmentation + endpoint detection response capabilities.

8. How to build data security and personal information protection? The fines are scary.

Answer: 2025 trend is “data masking + flow tracking + minimization principle”. Core three-pronged approach:

1. Complete data asset map (classification and grading);
2. Key data full-chain flow monitoring (DLP + database audit + UEBA);
3. Mandatory masking + access approval for important systems. Multiple companies have been fined ¥5 million + notices for not doing masking.

9. Should we build our own SOC or outsource MDR?

Answer: For annual security budgets < ¥8 million, strongly recommend directly purchasing mature MDR (Managed Detection and Response) services. Building your own SOC costs over ¥25 million in the first three years, with annual operating costs of ¥8-12 million, and 90% become “zombie SOCs” (only collect logs, don’t respond). MDR services currently offer the best cost-performance.

10. How much is enough for security construction?

Answer: International common practice (Gartner): security budget should be 6%-12% of total IT budget. Most Chinese enterprises are currently at 1%-3%, in a seriously underinvested state. In 2024, enterprises hit by ransomware paid average ransoms exceeding ¥3 million, security investment returns far exceed business systems.

11. Leadership only cares about one question: when can we “sleep peacefully”?

Answer: Never. But we can achieve:

• Discover attacks within 10 minutes;
• Control spread within 1 hour;
• Complete emergency response within 4 hours, business uninterrupted. This is already the real level of top global enterprises (Google, Microsoft’s post-incident response times).

12. Is security construction a one-time project or long-term investment?

Answer: Security is “operations” not “project”. Vulnerabilities emerge daily, attack techniques iterate monthly, 0days appear anytime. No enterprise globally completes security construction in one go. Correct approach: first year focus on construction (catching up), then annual sustained operational investment of 8-10% of IT budget.

13. Can we do a “free test” to see your capabilities?

Answer: Yes, but recommend paid red team assessment (usually ¥100-300,000). Truly capable attack testing cannot be free (requires 5-10 person/weeks of advanced red team). 99% of free tests are just running some scanners, not very meaningful.

14. How to meet localization requirements? Are pure domestic solutions reliable?

Answer: 2025 finance, energy, telecom and other industries mandate 100% localization of core system security equipment. Current domestic mainstream vendors (Qi An Xin, Sangfor, DBAP, Topsec, Venustech) have closed the gap with international vendors in traditional defense, but still have 2-3 year gaps in APT detection response capabilities. Recommend “core control plane localization + detection response plane appropriate mix”.

15. Should security construction be done by our IT department or completely outsourced?

Answer: Optimal model is “vendor construction + client operations + joint response team”. Security capabilities must be internalized, key positions (vulnerability management, emergency response) must be your own people, otherwise you’re giving keys to others.

16. We’re fully on some major cloud provider, is security handed over to the cloud provider?

Answer: Cloud providers only handle “below cloud” (physical facilities, virtualization, hypervisor) security, “above cloud” (identity permissions, configuration, application code, data, keys) is 100% customer responsibility. 2024-2025 has seen 50+ public major cloud leakage incidents, all customer responsibility zone issues. Typical cases: certain leading internet company’s public S3 bucket causing 200 million resume leaks, certain bank’s Redis without password leading to data theft, cloud providers only send alert emails, won’t fix for you.

17. Supply chain attacks are increasing, how can ordinary enterprises defend?

Answer: 2025 supply chain attacks exceed 40%. Enterprises must do three hard things: ① Mandate all third-party software to provide SBOM and continuous monitoring; ② All third-party remote operations must go through unified jump server + full session recording + behavior audit; ③ Key suppliers must undergo annual real red team assessment or penetration testing, otherwise no contract renewal. In 2024, a Fortune 500 manufacturing enterprise was fully compromised by a backdoor implanted through upstream MES vendor plugin update.

18. We’re already using AI large models, how to manage security?

Answer: 2025 regulations clearly require enterprises using generative AI to do algorithm filing + data outbound assessment. Enterprise side must implement three iron rules: ① Prohibit feeding personal sensitive information, trade secrets directly to public domain large models; ② Core scenarios mandate private deployment or enterprise API + local RAG; ③ All Prompts and model outputs must pass through DLP to block sensitive information. Multiple companies have been fined ¥2-8 million for employees directly feeding customer information to ChatGPT.

19. We have hundreds of subsidiaries/stores, how to unify group security management?

Answer: Group compromise 99% starts from the weakest subsidiary/store. Must build “group security brain”: unified asset fingerprint library + group-level CMDB + automated baseline inspection + graded authorization policy distribution + subsidiary security scoring ranking linked to performance assessment. Otherwise, no matter how advanced the group HQ builds SOC, it’s just “accompanying burial” for the weakest subsidiary.

20. What if we’re really hit by ransomware, should we pay the ransom?

Answer: 2025 regulations require post-payment reporting for ransomware payments. Professional advice: ① Must complete evidence collection, preserve images before payment; ② Historical data shows 35% probability of decryption failure or secondary extortion even after payment; ③ The only way to truly reduce payment probability is: offline + immutable backup + off-site disaster recovery drills (achieve RPO<4h, RTO<8h). Organizations with real recovery capabilities have single-digit payment rates.

21. Employee security awareness is poor, always clicking phishing emails, how to completely solve?

Answer: Traditional annual training effectiveness approaches zero. 2025 effective approach is “continuous + automated + strong punishment” combination: ① Monthly unannounced real phishing drills, no reports, just salary deduction notices; ② Email system mandatory automatic addition of “This email is from external” banner + attachment sandbox; ③ Coordinate with UEBA to automatically identify high-risk clicking employees, trigger secondary verification or temporary isolation. Enterprises adopting this approach can reduce phishing success rate from 25% to <3%.

22. We have multi-factor authentication MFA, why are accounts still being stolen?

Answer: Common three bypasses: ① MFA fatigue bombing (attackers batch push causing user mis-clicks); ② Adversary-in-the-Middle (Ngrok-type real-time relay); ③ Cookie hijacking (directly steal authenticated sessions after infecting endpoints). Must supplement: push-based MFA (digital/hardware tokens) + session binding device fingerprint + EDR real-time detection and removal of AitM tools.

23. Should we buy cybersecurity insurance? Is it worth it?

Answer: 2025 domestic coverage has increased to ¥100-300 million, premiums about ¥300,000-800,000/year. Worth buying, but must first meet insurance company hard prerequisites (full MFA coverage, EDR deployment rate >95%, regular red team assessments, offline backups), otherwise either rejected or denied claims. Real value of insurance is “transform uncertain large losses into certain small costs” + force enterprises to fix basics.

24. Who should manage industrial control/OT security? IT says not mine, manufacturing says can’t do it

Answer: 2025 regulations clearly define OT security responsibility主体 is the operating unit itself. Best practice is establish “industrial control security team” (IT 40% + process/automation 40% + external experts 20%), first do three things: asset inventory (including PLC, RTU models, firmware versions) → network segmentation (Level 3.2+ systems must have unidirectional gateways) → deploy industrial control specific anomaly detection systems. In 2024 at least 5 factory shutdown incidents over 7 days were from OT-side breaches.

25. How to do vulnerability management without becoming formalism?

Answer: 99% of enterprise vulnerability management is “scan - send report - nobody fixes - scan again next month”. Effective approach: ① Tag all vulnerabilities with asset importance + business labels; ② Only fix high-risk + core asset vulnerabilities (reduce from tens of thousands to hundreds); ③ Establish mandatory closure: vulnerability → auto-create Jira ticket → auto reduce permissions/disconnect network if not fixed on time. Achieving this step can stabilize core asset patch success rate above 95%.
