Defensive Ops › CDN Security
CDN Security — Your CDN can protect you, or quietly expose your origin
SIRI Security configures and hardens your CDN and edge security layer — WAF rules, DDoS protection, and origin server exposure — so it's actually doing the protective job it's capable of.

Growing gap
62% CLOUD
Cloud misconfiguration and IAM exploitation account for 62% of detections in cloud environments (DSCI) — the exact territory defensive ops work is built to harden.
Effective
31 JUL 2026
RBI's 2026 Framework expects demonstrable perimeter and access controls as part of continuous resilience, not a one-time network design review.
Baseline
70% MALWARE
Trojans and file infectors make up 70% of malware detections (Seqrite 2026) — relevant to how perimeter and endpoint defences are prioritised.
Baseline
6 HR WINDOW
CERT-In's notification window makes a hardened, well-segmented environment the difference between a contained incident and a sprawling one.
Extending
12–18 MO
RBI's historical pattern of extending bank requirements to NBFCs — defensive infrastructure expectations are likely on this same trajectory.
Hardened and kept hardened, not configured once and forgotten
What does CDN Security involve?
A CDN with a properly configured WAF and DDoS protection is a genuinely strong layer of defence — but a poorly configured one can create a false sense of security while your origin server remains directly reachable and unprotected.
We review and tune your WAF rules against real attack patterns (not just default rulesets), confirm DDoS protection is properly configured, and specifically verify that your origin server can't be reached by bypassing the CDN entirely.
Defensive infrastructure is tested, not just deployed
62% of cloud detections trace to misconfiguration and IAM exploitation (DSCI) — precisely the category ongoing cloud and network configuration management is designed to keep closed, not just check once.
SIRI Security delivers CDN Security to this standard directly — practitioner-led, documented, and connected to SIRI Law LLP's legal and regulatory response if a finding ever needs to go further.
What organisations get wrong
Four assumptions that leave defensive infrastructure exposed
Defensive controls configured once tend to drift — new services, new access grants, new integrations all quietly erode the original design.
01 — DRIFT
“Our network architecture was reviewed at launch”
Access rules, cloud configurations, and network segmentation drift constantly as an environment grows — a launch-time review doesn't speak to today's state.
02 — SCOPE
“Perimeter security covers our cloud environment too”
Cloud misconfiguration is now a leading detection category (62%, DSCI) — a traditional perimeter mindset alone leaves that surface unmanaged.
03 — ACCESS
“Access grants are reviewed when someone leaves”
Access control drifts continuously, not just at offboarding — periodic review catches privilege creep that offboarding alone misses.
04 — DELIVERY
“Our CDN is just a performance tool”
CDN misconfiguration can expose origin infrastructure or enable cache-poisoning attacks — it carries its own security surface, not just a performance one.
What CDN Security covers
What's included, start to finish
Defensive infrastructure hardened and kept that way as your environment changes.
01
WAF rule tuning
Rules tuned against real attack patterns and your application's actual behaviour, not left on generic defaults.
02
Origin exposure testing
Confirming your origin server can't be reached by bypassing the CDN.
03
DDoS protection configuration
Verifying DDoS mitigation is properly configured and tested, not just enabled by default.
04
Bot management review
Configuration to manage malicious automated traffic without blocking legitimate users.
05
SSL/TLS & caching security review
Certificate configuration and cache-poisoning risk reviewed together.
Evidence, not guesswork
No defensive ops programme vs. launch-time-only review vs. SIRI defensive ops
The gap between configured-once and continuously-managed is where drift quietly accumulates.

Why SIRI for CDN Security specifically
Defensive infrastructure managed by the same team that tests it
The practitioners who harden your perimeter and cloud configuration are the same ones who test whether it actually holds.
01
Directed by SIRI's Head of Cybersecurity
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
02
Findings connected directly to legal exposure
SIRI Security runs under the same roof as SIRI Law LLP — when a finding carries real legal exposure, the engagement can be brought under attorney-client privilege from day one, not bolted on after the fact.
03
Cloud-aware by default
Coverage explicitly extends to cloud and virtualization environments, where the majority of current detections actually occur.
04
Built for RBI's specific resilience bar
Hardening and review cadence are scoped to the standard RBI's 2026 Framework expects from regulated entities.
Who this is built for

Companies without a dedicated network security function
How we work
From scoping to ongoing delivery
01
Assessment & Design
We assess your current configuration and design the specific hardening or architecture changes needed.
Week 102
Implementation
Changes are implemented in coordination with your team, sequenced to avoid disrupting operations.
Weeks 2–303
Validation Testing
We validate the changes actually hold up against realistic testing, not just a configuration checklist.
Week 4+04
Ongoing Management
Where the service is ongoing, we continue to manage and adjust configuration as your environment evolves.
OngoingFrequently asked
CDN Security, answered directly
Which CDN providers do you support?
Cloudflare, Akamai, AWS CloudFront, and most major CDN/WAF platforms.
Can you test if our origin is actually hidden?
Yes — origin exposure testing (confirming the CDN can't be bypassed) is a core, and often eye-opening, part of this engagement.
How long does this take?
Most engagements in this category run 2 to 6 weeks depending on environment size and complexity.
Do you manage this ongoing, or is it a one-time project?
Both models are available — we scope this as a one-time hardening project or an ongoing managed service depending on what you need.
Harden it, then keep it that way
Scope CDN Security.
Most engagements start with a configuration review before scoping ongoing management.
